Demon

Demons (悪魔) are a species of malevolent monsters that appear both in YGGDRASIL and the New World.

New World
Demons are considered by the New World inhabitants to be otherworldly monsters that hail from the Demon World. Apparently, demons have been a prevalent part of the ancient history left within the New World to be told by its inhabitants.

Two hundred years ago during what historians called the Demon God Unrest, a group of demons were led by a being called the Demon God. These Evil Deities led by the Demon God brought with them countless deaths and destruction throughout many lands across the New World. As a result, there were numerous kingdoms from the heteromorphic and human race who fell before their chaotic rampage.

In that time period, it was believed these demons held the power to destroy the world, as there were none who could possibly challenge them. However, it was only thanks to the Thirteen Heroes who defeated them one by one that the New World was able to be saved from the brink of destruction.

Types of Demons
Regarded as otherworldly existences that are atrocious monsters, which exist solely for the extermination of all sentient and good living beings. They are also synonymous with the word 'evil'. Thus far, demons have been classified into two major categories: Though there are various sub-types ranging from beast to humanoids:
 * Demon: Those who use violence to bring about destruction.
 * Devil: Those who use their intelligence to bring about depravity.
 * Devourer
 * Gazer Devil
 * Hellhound
 * Light-Fingered Demon
 * Imp
 * Shadow Demon
 * Succubus

Appearance
Demons come in a myriad of forms and appearance. Befitting of creatures that feed off the suffering of others, they may resemble horrible grotesque monsters.

Abilities
As with their appearance, demons possess a variety of unholy abilities although these depend on the ranking of the demon itself. On the other hand, many demons alike were resistant to the fire element. Also, even the likes of hazardous environments would have no negative effects on them whatsoever.

Culture
Demons seem to follow a hierarchy of sorts in the New World. Strangely, according to some humans, if a demon wants to show up in the New World, it has to engrave its name into the world. Therefore, they can’t use false names. Experiments show that demons using a false name might even cause them to disappear on the spot.
