Incubus

Main

Extra

An incubus is the male counterpart to a monster, and represents the eventual fate of (most) males exposed to high levels of mamono mana. Unlike female monsterisation, where the physical and mental change from human to monster is rapid (in some cases taking only moments ), for incubi the process is usually much more gradual and open-ended. Just as monster girls become more and more powerful the more sex they have, so do incubi, with increases to lustiness, physical attributes and lifespan .

Incubi are said to be "an ideal male to a female monster", therefore many monsters are eager for their mates to transform faster so they can enjoy the changes. Monsters with a lot of mamono mana at their disposal, like dark matters or khepri, are noted as being able to effect the change quickly, but the majority of monsters must just rely on lots and lots and lots of sex. Certain items which can expedite the transformation, like Succubus Nostrum, may be sought by eager wives.

Although the vast majority of information on incubi pertains to human men, elves can definitely become incubi and there seems no reason that any of the few male dwarves left can't do so as well (or rather that they didn't already become incubi some time ago), as dwarf men are also considered a type of human. It is also confirmed that male angels can become incubi.

A Being That's Convenient For Monsters

Physical changes

The biggest changes of all occur in the functions that are also most important to monsters that get used during sex. It depends on the race and preferences of the monster that one is coupled with, but most men who become an incubus will have their penis grow larger by leaps and bounds, and they'll be able to please monsters even more. The amount of semen and spirit released from there will be incomparable to when they were human, and they'll have boundless stamina so that they're able to release it again and again without getting exhausted.

Besides genital gargantuism, incubi do not receive (permanent) drastic physical changes comparable to, say, an arachne's abdomen or a succubus' wings and tail. They do, however, see disposal of features that impeded their sex lives previously, such as corpulence or the general frailties of old age.

There are changes under the skin for an incubus too. Stamina increases to monster-like levels as the power of mamono mana suffuses their body, and incubi gain some measure of the environmental resilience of their monster partner (e.g. heat resistance for a lava golem's mate, breathing underwater for a Sea Bishop's mate, night vision for the mates of nocturnal or cave-dwelling monsters). Like a succubus, they also gain the ability to actually sustain themselves on their partner's mamono mana in place of food.

An exception to the lack of drastic changes are the husbands of the various chaos/abyss-aligned monsters (such as atlach-nacha and mindflayer), which gain the ability to change into completely non-human or only vaguely humanoid forms. These forms can be reverted to normal human form at will, at least after the initial forced transformation, and thus are not considered a permanent transformation.

Mental changes

On first being attacked by a monster girl, humans are likely to be consumed by an instinctive fear and revulsion at their demonic appearance. Such atavistic terror and Order moral objections are thrown aside with the transition to an incubus: Their thoughts and values change, all becoming centered around having sex with monsters . Lust skyrockets to keep pace with the monsters' insatiable hunger for sex, and their interests in other things (like work and hobbies) can potentially change, as sexual activity becomes a more important part of their lives. There is a lot of variety though depending on the inner nature of the man, some incubi lead completely "normal" lives during the day, restricting sex to night and having it replace most of their sleep as it is just as energizing for them:

Also, after being completely charmed by a monster, one's aesthetic sense will have changed so that he feels that the grotesque parts and organs of monsters are beautiful. Other than that, one's sense of time, and values concerning work and recreation will also change so that it becomes more convenient to live with monsters.

Incubi never get bored of sex or lose the mood after doing the deed; they can keep going indefinitely thanks to exchanging energy with their mate in a constant cycle. Whereas a human first being attacked by a monster is likely to pass out from pleasure before his monster girl partner is close to being finished with him, an incubus can go until perfect mutual satisfaction is reached, and incubi with harems can flip the dynamic on its head and "end up being unable to be satisfied, unless he has sex with all of the monsters in his harem".

Mana changes

When women undergo monsterisation, their essence production ability (which is weaker than men's to start with) gets extinguished entirely and they become a creature with only mamono mana inside them. The same does not occur with men and incubi, instead there is a large improvement in mana production in response to increasing amounts of mamono mana within their bodies.

The mamono mana that enters a man, "marks" an incubus with his partner's uniquely-scented mana. There is a general understanding that other monsters will not randomly ravish a man who has been claimed like this, albeit should another monster fall in love with him then the marking will not be a barrier to her love and a harem will form instead. Although most human women can't detect it, the mamono mana can have a drastic effect: if an incubus has sex with a human woman, his semen will monsterise her. Notably though, no incubus is known to have ever had sex with an unwilling woman, and excepting if they already were in love with a human woman, their lust naturally is directed toward monster girls anyway.

Daily lives

Although the sex drive of a man who has become an incubus is greatly enhanced, causing sex with their monster partner or partners to be a greater part of their life, incubised men are still free to pursue previous hobbies and work from before incubisation. This often results in monster nations exporting produce to other nations, sometimes producing goods that can only be created by a monster and her husband, or are only available in mamono realm lands.

A large cultural shift has begun amongst the monsters more recently, with monster wives taking a keener interest in more human activities, whether it be culinary or a craft. Many of these changes have occurred as monster women have sought to improve the lives of their husbands, helping to keep them happy. Many single monster women have also taken up crafts to further impress potential mates, instead of directly assaulting them. It is noted some of these changes are due to things their human husbands have taught them, and that incubi and monsterized women have spurred much cultural development among monsters as a whole.

True Nature

In World Guide 3, the baphomet Runya Runya shares convincing arguments that incubi and heroes are essentially the same type of being. That is, they are humans that have broken the "shackles" that are thought of as human limits, the only difference ultimately being that where heroes have their shackles broken by divine power (or sometimes other sources of energy), incubi utilize mamono mana to remove their limiters. The powers and/or abilities they gain after breaking these shackles (aside from spells and abilities specifically dependent on gods or monsters) are their own, and remain even if (for instance) all divine power is removed from them. Heretical theologians theorize that humans were created as beings with unlimited potential (that was for unknown reasons and by unknown parties later shackled), and that rather than becoming a new type of being, heroes and incubi are merely regaining the abilities they were meant to have all along.

Further evidence for the lack of meaningful distinction between heroes and incubi can be seen in how most every ability (including sexual ones) gained by incubi can potentially be gained by divinely blessed heroes and vice versa. Notably, humans blessed by Eros to become her version of "heroes" gain (among other things) sexual abilities on par with incubi.

Research into all this, however, is forbidden by the Order, and thus monsters and monster-allied humans seem to be the only ones studying just what heroes and incubi really are.

Book Information

Incubus (MGE-1)

Incubus

Human men who have been violated by mamono mana, whose nature is vastly changed. They are often also treated as monsters, but technically all monsters are female, so no matter what, the incubi are just humans who have taken their nature from monsters.

Transformation into an incubus

Transformation into an incubus mainly occurs when a man continues to have sex with a monster, continuously receiving her mamono mana in his body. After becoming an incubus, their physical appearance hardly changes at all from when they were human; however, they gain vigor and lust like that of a monster, far exceeding that of a human. Their thoughts and values change, all becoming centered around having sex with monsters. Their body also gradually changes to become more suited to having sex with them. In addition to ordinarily eating food, just as the monsters sustain themselves on essence, the incubi become able to live by sustaining themselves on the monsters' mamono mana Through this, the lifespans of the incubi are also extended to match that of the monster whose mamono mana they use to sustain themselves. Furthermore, both the volume and quality of the essence produced inside their bodies increases by leaps and bounds. They are an extremely convenient existence for a monster. It's probably fair to say that they are the equivalent of male monsters.

By continuously having intercourse with a monster from the succubus family, a man can be transformed into an incubus comparatively far more quickly; however, even in the case of the other monsters, after spending a long period of time at her side as her husband and having frequent intercourse, a man will probably eventually change into an incubus even though the changes are very gradual. Among the monsters, there is a medicine made from the mamono mana of the succubus in circulation that is called “succubus' nostrum.” Many monsters like having their husbands drink it in order to try to change them into an incubus more quickly. Also, the incubi possess the same kind of mamono mana inside their bodies as the monster who changed them into an incubus, and if they have sex with human women, the women will be transformed into monsters.

Incubi (MGE-II, p15)

Human men generally become incubi by absorbing a large quantity of monster mana through repeated sexual contact with monsters. Incubi are sometimes considered male monsters. Strictly speaking, however, they are humans whose abilities have been enhanced by mana. While they are identical to humans in appearance, their libido and potency far surpass that of a human's - all the better to serve monsters as their companions - and their minds become utterly dominated by thoughts of intimate relations with monsters.

Incubi may adapt to the environment in which their accompanying monster resides. For instance: they may become capable of living underwater or develop a resistance to heat or cold. The most important changes, however, rest in the fact that, just as monsters live on the sustenance of their husbands' essence, an incubus can live on a monster's mana. This allows an incubus-monster couple to live in endless debauchery, which fills the incubus with life, keeps him from aging, and extends his years to match those of his monster mate. Because all monsters wish to spend their lives with the men they love, a monster who has acquired a husband is sure to ravish him into an incubus as soon as possible.

The Incubus (Fallen Maidens, p77)

An incubus is mainly a human man that kept receiving Mamono mana, and containing it within his body, resulting in a transformation into a being that's convenient for monsters, possessing superhuman stamina and lust. Under the current concept, monsters are all female beings that only possess Mamono mana, so an incubus, which is male, and possesses both mana and Mamono mana at the same time, is not a monster. Ultimately, they're just humans altered by Mamono mana. However, the Order regards them as being the same as monsters, and they're targeted for expulsion and suppression.

1. Until Changing Into An Incubus

Compared to monsterisation, in which changes suddenly appear, changes caused by incubisation are extremely gradual. Unlike a woman's monsterisation, where they totally change into a monster both mentally and physically after having sex one time, the changes that occur when a man transforms into an incubus and afterward, appear bit by bit each time he has sex with a monster.

Human men transform into an incubus by having sex with monsters, and having Mamono mana poured inside of them. Unlike women, who recover mana by absorbing it from the air, men continue to produce mana within their own body, so compared to women, it's more difficult for Mamono mana to take hold, and they do not change into an incubus just from having sex once.

In the case of the succubus family of monsters, they possess “succubus' energy” which has a higher retention rate, and causes men to release more mana in a single session of sex by infusing them with it, so compared to other monsters, incubisation is extremely fast, and in the case of a powerful succubus, it's even possible to change a man into an incubus by having sex once.

Also, even if it's a monster of another race, after spending a long time as their husband, and living beside them, by continuing to have sex, Mamono mana gradually takes hold in the body after each time, and eventually, a man will transform into an incubus.

Additionally, even monsters not of the succubus family can accelerate the incubisation process by continuing to ravish a man with multiple monsters, and aside from that, there is “succubus' secret elixir”, a medicine made from succubus' energy, and there are special rituals and spells that can be used to quickly change a man into an incubus.

When transformation into an incubus occurs, it's not like one can clearly tell that he's transformed, as was the case when a woman is monsterised. In the case of monsterisation, a woman is able to grasp that she's become a monster because of the changes in her body, and a feeling of ecstasy like she's been reborn, but in the case of incubisation, before one knows it, he's already changed into an incubus.

In the course of getting continuously violated by monsters over and over, a man who at first would tire soon, exhaust his mana, and pass out, will steadily increase the amount of time he can have sex, and the number of times he can release mana increases. In the beginning, the pleasure is so violent that one can't even think straight, but one gradually becomes able to enjoy the pleasure. Gradually one will change so that he can't help but consider having sex with the monster in front of him, and gradually, he'll come to desire to be ravished by the monster before his eyes. In this way, bit by bit, one will change into an incubus without being aware of it.

What makes an incubus an incubus, and a man a man is the mana within his body and the existence of a mana production faculty. Very rarely among the incubi, there exist those who unconsciously destroy their own mana production faculty. In that case, mana will not be produced, and the body of an incubus who loses mana and is completely ruled by Mamono mana will completely change into a monster. This monster is called an “Alp (encyclopedia – p. 108). The process of changing into this monster is described on p.92 of this book.

2. Mental and Physical Changes Caused by Incubisation

As for changes caused by incubisation, the changes that appear basically make it convenient for the monster that one is coupled with.

First, it is purported that the looks almost don't change at all compared to when one was human. Monsters don't care very much about the attractiveness of a man's face, so in most cases there are no changes whatsoever. The body changes to become more healthy and durable so that it's convenient for sex, but it's rare for the appearance to change greatly other than that.

A rare exception occurs and the appearance greatly changes in the case of those who are too feeble or fat, and their form will be vastly improved so that it's convenient to have sex with monsters. Also, in the case of those who are so old that it's a hindrance to sex, they will also be rejuvenated.

After one has changed into an incubus, the mind also changes so that one's values become nearer to those of the monsters, but compared to monsterisation, even if only a little bit, human-like values from the period when one was a human will remain. However, the values and thoughts of an incubus, a being that became a monster's prisoner so much so that it altered the nature of his mind and body, will change to become eager to have sex with monsters. One's lust will swell up like that of the monsters, and disgust towards monsters and sex, etc. will have long since disappeared, and one will change so that he aggressively desires sex with monsters.

Also, after being completely charmed by a monster, one's aesthetic sense will have changed so that he feels that the grotesque parts and organs of monsters are beautiful. Other than that, one's sense of time, and values concerning work and recreation will also change so that it becomes more convenient to live with monsters.

The biggest changes of all occur in the functions that are also most important to monsters that get used during sex. It depends on the race and preferences of the monster that one is coupled with, but most men who become an incubus will have their penis grow larger by leaps and bounds, and they'll be able to please monsters even more. The amount of semen and mana released from there will be incomparable to when they were human, and they'll have boundless stamina so that they're able to release it again and again without getting exhausted.

The quality of the mana is also remarkably different. It becomes so much thicker, stickier, and sweeter, that it's incomparable to when they were human, and one lick will make a monster melt. Also, human men sometimes lose the mood after expelling mana, but it doesn't occur in an incubus, and their lust for monsters just flares up.

In addition to the normal food that they ate when they were human, it's also possible for an incubus to feed on Mamono mana by having sex with monsters. For that reason, an incubus never gets exhausted when having sex with a monster. Instead, their entire body will brim full of lust and energy due to Mamono mana. When the body of an incubus obtains Mamono mana by having sex with a monster, it will immediately produce mana. When this mana is released to a monster, the monster will produce Mamono mana from it and pour it into the body of the incubus.

Astonishingly, with this cycle, not only does the total amount of magical energy not decrease, instead it continues to increase, so it's possible for a monster and an incubus to keep having sex almost forever, and as long as there's one incubus and one monster, it's possible for them to live by just having sex. As far as the divinities and the Order are concerned, this nearly perpetual cycle is something that is in violation of divine providence that will greatly throw off the laws of the universe, and is extremely viewed as a problem.

Also, it's said that the lifespan of men who become an incubus becomes dramatically longer. Since they can keep living by having sex with each other, their lifespan is roughly the same as the monster that they're coupled with. Just like monsters, their appearance stops aging at a certain stage. It could be as a boy, as a young man, or as a mature man. Since an incubus is a being that's convenient for a monster, they change depending on the tastes of the monster that they're paired with. In this way, an incubus is none other than an ideal male to a female monster.

The power of an incubus grows stronger the more Mamono mana they accumulate. In the case of those that periodically have sex with multiple monsters, it piles up, so in the case of a single incubus that makes a harem of multiple monsters and keeps having sex with them, it ends up causing the birth of an extremely powerful incubus. Regardless of how many monsters are in the harem, an incubus has limitless stamina and lust, and can have sex with all of them. Even if an incubus keeps having sex with them day and night alternatively for a period of several days, he'll never get tired, lose his erection, or feel pain or boredom. On the contrary, he'll end up being unable to get satisfied unless he has sex with all of the monsters in the harem, and it'll even get to the point where it's as if spending several days having sex with all the monsters in the harem is like having sex one time to him.

Additionally, those who become an incubus can also adapt to the environment to match the monster that they're coupled with. For example, an incubus coupled with a monster that lives in a desert, or near a volcanic crater, will gain resistance to heat, and an incubus that is coupled with a monster from a snowy country will gain resistance to cold. They gain such strong resistance that they can even actively have sex with monsters in such environments. To provide a remarkable example, due to a ritual performed by a “sea bishop (encyclopedia I – p. 116)”, there are incubi that became able to live underwater. This ritual is performed to quickly change someone into an incubus, so as a result of having been changed into an incubus with the Mamono mana of the monsters of the sea, they've adapted to live underwater.

Since an incubus retains the Mamono mana of the monster he's coupled with inside his body, a human woman who has sex with an incubus will end up transforming into that race. However, the lust of an incubus who's kept having sex with monsters will not be satisfied by having sex with anyone other than a monster.

Also, an incubus' superhuman lust is only directed towards the monster he's coupled with no matter what, and they don't have an instinct to attack the opposite sex like monsters do. For that reason, incubi do not attack and forcibly rape human women, and such an incident has never been confirmed.

Topic - Heroes and Incubi ~The Unfettered Ones~ (Sabbath Grimoire, p71)

All living things fundamentally have an upper limit to the amount of mana they can contain within their body. Mana is vital energy, the power that life itself possesses, i.e, there are established limits to the amount of power that a race can possess. Humans are no exception to this rule, either, and there is a limit to what is humanly possible. Even if one reaches his limit as a human being through effort and talent, his power will never exceed that of greater monsters and gods who possess high abilities far beyond human limitations. But those who become “heroes” and “incubi” are able to possess even more mana. Through continuous training, they can not only acquire power surpassing that of monsters, but even that of gods. These are beings who have had their human “limitations” removed when some factor caused more mana than a human being is naturally able to possess to dwell within the human body. It is as if their “shackles” are destroyed by the overflowing mana. When this is caused by divine mana, that man is called a “hero”, but on the other hand, when it is caused by mamono mana, that man is called an “incubus”.

Despite the distinction drawn between them, “heroes” and “incubi” are virtually the same kind of beings. The only difference is whether the limit was removed at the hands of a god or a monster. They're “heroes” because they fight with the chief god's blessing, and they're “incubi” because they're monsters' husbands. They can be differentiated in such fashion by where their allegiances lie, but no matter what method of biological classification is used, it is impossible to draw a clear distinction between the two. There is a method of distinguishing them based on their differing abilities and whether they possess divine mana or mamono mana within their bodies, but neither is sufficient for accurate classification. Basically, heroes, who are beings that have received the blessing of the chief god, tend to have their abilities increased so that they may fight to impose her will; while on the other hand, we can say that incubi are beings who have received a monster's blessing, and changes based on the monster's lust for pleasure such as increased sexual potency and stamina appropriate for having sex with a monster can be observed. However, they are both beings with superhuman growth potential. On the one hand, you have someone who trained repeatedly seeking the power to fight, and on the other, you have someone who copulated with a monster countless times, but they both have achieved a corresponding amount of ability growth, and that's all there is to it.

Hence, for example, if an incubus desired to master swordsmanship, or continuously trained himself in pursuit of power to protect his wife and children, he could also gain superhuman physical abilities and durability like a hero in addition to his superhuman sexual stamina. Then, in terms of having enhanced combat abilities, it becomes impossible to distinguish them from the chief god's heroes who have obtained power in order to fight monsters. On the other hand, as explained in “Heroes Viewed As 'Human Males'(p.71)”, just like incubi, heroes also have superior abilities as males. What's more, heroes granted power by the goddess of love, “Eros”, acquire increased sexual stamina and potency to enthrall their partners, so it can be seen that the nature of their empowerment is very similar to that of an incubus. And in the extreme case of the half god half monster “fallen god”, they become beings who are both heroes and incubi, bearing half divine mana and half mamono mana.

Also, in some cases, there are those who become “beings who transcend human limitations”, like heroes and incubi, even without the intervention of a god or monster. In such cases, there is something that removes the shackles of humanity, but the person himself will usually not even be cognizant of it. The distinction between incubus and hero is made even more tenuous due to these ambiguous beings who are difficult to classify. An example of a factor that could cause this is remaining in lands teeming with mana for an extremely long period of time. Sometimes legends about such places are handed down with claims like “if you train in this land, you can acquire inhuman power”. It seems likely that the source of such legends is people who acquired superhuman power by continuously training in those lands. For instance, in the case that the location is a land teeming with divine mana, then it can be inferred that the shackles of humanity were removed due to the influence of divine mana, and as such, the person would have transformed into a being who is very nearly a “hero”. On the other hand, training grounds where monsters who seek to master martial arts such as “jinko (Encyclopedia II- p. 168)” and “hinezumi (Encyclopedia II – p.174)” gather are lands teeming with mamono mana, i.e, there is a possibility that they have become mamono realms. Humans who accumulate training in these special mamono realms can acquire power enough to rival monsters, or sometimes even power surpassing that of monsters. In this case, he would become a being very nearly an “incubus”, but either way, the man himself would be unaware of it, and the Order wouldn't recognize it either. He would still be treated as “human” in human society regardless, so long as he was lacking a monster wife.

Also, sometimes the shackles can also be removed due to influence from others. A human man who has continuously been practicing swordsmanship with a “lizardman (Encyclopedia I – p.66)” since they were little will lose his shackles before he knows it and gradually acquire enough power to rival her. Human craftsmen who continuously study with races who possess advanced crafting skills such as “dwarves (Encyclopedia I – p.100)” and “gremlins (Encyclopedia II – p.158)”, acquire godlike skills, determined not to be outdone by them. In this manner, by having well-matched friends and rivals to compete with, as if boosting each other, they can transcend their humanity and gradually grow even more powerful. When men finally obtain enough power to subdue “dragons” after continuing to challenge them countless times, it's also the same sort of thing. It can be surmised that what's probably happening is that mamono mana intermixed during battle when confronting a dragon responds to a man's desire “to acquire power exceeding that of the dragon and make her mine”, resulting in the destruction of his shackles and the fruition of all his accumulated training. In this case too, as expected, the man would become a being that is very nearly an “incubus”, but he would probably mostly be mistaken as a “hero” who acquired enough power to defeat a dragon by the majority of humans, who are incapable of sensing mana.

Other than that, shackles are sometimes removed from being hit by spells. Rarely, there are tales of those who acquired mana over the human limit by having survived after nearly dying from being hit by a big spell. Also, aside from that, if a forbidden degree of healing is performed using the hieromancy spell “miracle of restoration (p.67)” such as regeneration of lost limbs or treatment of deadly diseases, the patient may awaken as a being that is very nearly a hero. In most cases, the factor that caused the unshackling is indeterminable. Among them, there are those who broke the limit themselves by continuously accumulating training even after reaching the human limit, and even those who are thought to have never had any human limitations in the first place for some reason. As expected, these “beings who transcend human limitations” are pretty much the same as heroes and incubi. The only thing that distinguishes them is the fact that they have neither divine mana nor mamono mana in their body. Additionally, if they were to take divine mana within their body by acquiring hieromancy, or take mamono mana within their body by obtaining a monster wife, then there would probably no longer be any way of distinguishing them from heroes or incubi.

In this way, the boundary between “humans”, “heroes”, “incubi”, and “beings who transcended human limitations” themselves is extremely vague. Biologically and magicologically, they're nothing but “strong humans” who just took different paths to get there. It is difficult to accurately classify them, and ultimately, the current classification is done out of convenience to reflect their origins and allegiances. While they are more or less the same kind of beings, the way that they are treated is based on this convenient classification. Primarily in human societies under the control of the forces of the Order of the Chief God, incubi are treated not as human, but as inhuman monsters. In the Order of the Chief God, any attempt by humans to uncover the secret mechanism behind heroes, a miracle of the gods, is regarded as an outrage against the gods, so open research is also forbidden. Humans generally conceive of heroes as holy beings anointed by the gods and the Order, while “incubi” are evil beings who became monsters themselves after having been imprisoned by monsters. That's sort of how it is. For that reason, those who transcended the human limit themselves mostly also tend to be mistaken as either one or the other.

Furthermore, all other living things besides humans also have a limit to their abilities and the amount of mana they can possess. Naturally, there are limits for monsters too, depending on race, but in the case of monsters, the “limit” is easily removed by repeatedly obtaining a man's essence, i.e, among monsters, unmarried individuals correspond to “ordinary humans”, and we can say that married individuals who have obtained a human husband and received his blessing, repeatedly copulating all day and night, correspond to “heroes” and “incubi”.

There is a hypothesis once posited by biologists which claims that if one were to possess mana in excess of the human limit, i.e., vital energy, the power would be far too tremendous for the mind and body to tolerate, but it has been confirmed that in the case of sudden incubization induced by being showered in highly condensed mana, the body and mind also naturally become stronger along with the increase in mana, so that hypothesis has been refuted. The following is a speculative theory among heretical theologians: “Humans are creatures who were created with unlimited growth potential in mind from the very beginning. To become an incubus or a hero is not to transcend one's humanity, but to assume one's rightful original human form. Isn't the present condition of humanity in fact the result of some sort of limit being imposed on us?“

Since the previous hypothesis has been refuted, and there is the existence of those who overcome human limitations without the intervention of monsters or gods, it lends credence to this theory. On top of that, the author will add in her own theory too, but the fact that the effects of “miracle of recovery”, “miracle of power”, and so on, are confined to what is “humanly” possible, regardless of the fact that they can theoretically produce even greater effects, may not be due to the caster lacking the required abilities or mana amount. Instead, it really does seem likely that some sort of “limit” has been put on spells and blessing granted by the gods.
