World Guide - Side II Book Entry
It is not unusual for knights going into battle to wear a blessed amulet, the same custom exists with the dark knights. The medallion belonging to the dark knight is just such an amulet. Amulets, that are worn by the dark knights, are some kind of jewelry: necklaces, brooches - it can be any kind, but what they all have in common is the presence of a small metal plate with an engraved name. These amulets of the dark knights are based on the traditions of the warriors of the Kingdom of Lescatie, the amulets they used in the past when knights and ordinary soldiers of the Order went to battle with monsters. According to one story, a simple soldier of the Order once carved the name of his beloved on his weapon as a talisman to return home safely afterwards. As the story goes, finding himself in a country filled with countless monsters, he actually managed to survive and returned safely to his homeland. This story seems to have spread among knights and soldiers and made it popular to wear an amulet on which, to avoid the monsters, the name of an important person - a family member or lover - is inscribed.
When Lescatie became a mamono realm, the Mamono improved these amulets by beginning to make them from the demonic ore "Druelite," which can enhance magic. A "no name" talisman will have no effect, but a hand-carved name of a loved one on a Druelite plate will have the effect of a protective rune shielding that person. Strengthened magic of such runes will turn into a protective field that will envelop the body of the owner. In other words, this amulet is a magical object which will show its true value only in hands of your beloved partner.
After some time, the magical field of protection will be depleted, but if you engage in sexual activity, as a married couple should, the amulet worn around the neck will absorb the excess mana and you can use it again. For dark knights, this amulet is a symbol of love and affection that has been bestowed by a loved one. Wearing the amulet is the equivalent of proclaiming, "I have a partner with whom we walk the road of life!" It seems that dark knights who wear such amulets are often looked upon with respect and envy by other knights who have not yet acquired husbands.
In the equipment store of Castle Salvarision there is still a large number of "nameless amulets." And since many dark knights of both sexes wear their Amulets all day, not just during intercourse, there are occasional situations where abusers misunderstand dark knight's amulets as "proof of knighthood". Therefore, they wear amulets without a name to disguise themselves as a dark knight, but it can be said that this is completely counterproductive. Wearing an amulet without a name engraved on it is like admitting you don't have a spouse. If you wear one in Lescatie, you'll be spotted in no time by mamonos who have no husband, who will think, "I'll engrave my name on your talisman!" [1]
