Dragonium is a rare magical ore mined from rocks found almost exclusively in the continent of Dragonia. Similar in nature to Mamono Realm Silver, Dragonium instead tends to form in areas where the Mamono Mana of Dragon Monster Girls is prevalent. The material is described in detail in Monster Girl Encyclopedia World Guide - Side I: Dragonia book.
World Guide - Side I Book Entry
Dragonium is a rare ore mined in Dragonia.
The following is said about this mamono realm ore: "It appears in the same way as mamono realm silver, but under the influence of the powerful magical energy of the dragons, it changes its properties over time. But since the Dragons' energy is mostly concentrated in the air, Dragonium is primarily formed in those places where the veins of mamono realm silver come to the surface due to the collapses of the ground hiding them. A solid crystalline body forms on the surface in such places."
In other words, Dragonium is found only in places where strong magical energy drifts, such as in the dark mamono realm of Dragonia, where it is dangerous for humans to enter. That is why this ore has such a rare distribution. It is mostly found in the caves and ruins of Dragonia where the magical power remains. But the most famous place of origin of these crystals in Dragonia is the "Graveyard of Dragons", the home of dragon zombies. Several times a year, there are witnesses who see adventurers blinded by greed who head for the graveyard in search of Dragonium. But the results of their forays are easy to imagine.
Dragonium has a characteristic called "dragon's breath". This "breath" has the property to "dissipate magical energy" when mixed with precious metals. For example, armor and shield made with Dragonium can decrease magical attacks by dissipating it. And when processed to make weapons such as swords and spears, magical attacks are spread more widely than usual. The rare abilities that Dragonium possesses are very useful even to us dragon knights. In a passionate encounter with a dragon, men who have not yet become incubi are often exposed to strong magical energy, as well as the accompanying old dragon's physical power. If you wear an accessory using Dragonium and it touches your skin, as in the case of a pendant or necklace, fatigue during sexual activity will decrease and the time of reaching orgasm will decrease, and incubization of the body will not occur. But I must warn you. If you're looking for easy power or inexperienced in controlling magical powers and easily grabbing weapons from this ore, you won't be able to hold the dragon's power. If that happens, it will only be a great feast for the beautiful mamono attracted by the release of your delicious spiritual energy. For these reasons, Dragonium weapons are mostly purchased by demons from the radical faction or mamonos with special abilities, and armor by single men who have not yet become incubi. When buying, men may have to demonstrate to the vendors how they control their energy to see if they are fit to handle the weapon, or they may have to undergo personal training. Even our dragon knights are not allowed to use weapons with Dragonium inclusions until after they've been fully titled. Of course, when you become part of the Dragon Order, you will be granted a Dragonium spear.
Although it is not bragging, Dragonium was also used in the creation of my weapon. This Dragonium, which might be called a symbol of our race's power, is of little interest to you? Then I can help you take the first step to becoming the dragon knight that no doubt you are... ♥
