Demons

Demons are one of the supernatural species that exists in the world. They reside in their domain known as Hell. Demons also have 72 Dukes of Hell, and are divided into two factions between the two leaders—Lilith, the Mother of Demons, and Diablo, the Incarnation of Evil.

Description
Demons are creatures who were rejected by God for being too corrupt. Once angels who were on God's side, but now cast out of paradise and abandoned in the confines of a world in decay. Punished by the creator himself to be the representation of all the 'evil' of humanity. Condemned to roam the seven hells for all eternity, demons are the result of a single action—Sin.

Creation
Demons are created when people kill in anger, envy other people's goods and steal those goods, when people are too lazy to do something, when people are very proud and believe they are always right, consequently harming another being, when people have an insatiable gluttony and do not share with their peers despite having better conditions, when people accumulate enough goods without need, and when people have an uncontrollable lust, that can lead to the death of other beings. When a 'sin' is committed, by divine law, they will be condemned to hell. However, by God's will, their sins are still to be judged by the three Judges of the Abyss. These judges are gigantic beings whose only visible features are their golden eyes, golden hands, and a mouth that seems to contain an entire 'galaxy' inside it. Supernatural beings call these judges the eyes, hands, and mouth of God, because with one decree from these formless beings, they can be condemned to eternal happiness, or eternal suffering.

If an individual's sins are declared to be too high to redeem, the mortal soul will be thrown into the confines of the 7 hells, its' soul will be recycled, taking only the good part, and all that is left will be an empty shell of pure evil. These are the beings known as demons. People of antiquity believe that there is no 'goodness' in demons. After all, that part was taken from them a long time ago.

History
Lucifer is the first Demon King and Guard of hell, who was also responsible for keeping demons in hell. However, the man decided to simply take a vacation; he broke the key to the gate in two and gave it to his most faithful 'friends';

Lilith, the Mother of Demons, also known as Adam's first wife, who rejected being 'chained' by god. She subsequently became the Queen of an entire faction. However, she is a special being, because despite being a demon of the highest rank, whom can be considered an evil god, Lilith still retains her 'goodness' unlike other demons.

The other half of the key was then given to Diablo, also nicknamed 'Satan' by mortals. Later on, he became the Demon King Diablo, who was the leader for which Belial served. Diablo is hailed as the incarnation of evil, the bloody plague, the demon of Chaos. There are many titles that beings have given him. Diablo is the first demon born when God implemented the soul recycling system, humanity's first sin, and, consequently, by being the first and beginning of everything, he is the 'idealization' of what demons should be. From then on, the hierarchy of Hell was split between two factions, warring for dominance over the other.

Factions
Hell is currently divided into two factions, Lilith's faction, and Diablo's. The main objective of Diablo's faction was the control and dominance of the human race, so he wanted war against humans.

Abilities
Demons possess a supernatural longevity, and superior strength and speed compared to humans. However, the most common abilities of demons is their ability to possess and consume souls. By possessing deceased souls, demons can manifest their selves in the mortal world through the use of these vessels. Alternatively, demons can also choose to consume these souls instead of using them as vessels, which in turn can help to nourish them. However, eating souls is generally discouraged in Hell, since souls are becoming scarce, and each available soul would much preferably be used to manifest their demonic kin on Earth.

Restrictions
Demons have a divine rule that prohibits them to intervene on Earth. Additionally, there is a 'door' that prevents the passage of demons, and at that door, there was a guard—Lucifer, the first Demon King and Guard of Hell.

With the key to hell's gate broken, the gate itself went into a state of instability, and 'gaps' began to appear in the gate. Through these breaches the Dukes and Kings could send minions into the human world. At the time, the strongest demons were excited when they saw the breach in the gate. They thought they could finally get out of this boredom that is hell and wanted to go to the human world. Unfortunately, they couldn't, only low level demons could go through the gate. Moreover, there were two options for high level demons. They can either seal their power and enter the human world with the power of a low level demon or possess a human's body.

Sealing off their power was a big 'no' for the demons, considering they didn't know when their friends would turn their blades on them. Thus, it became a general agreement that demons would possess the bodies of humans who had just died, and, by using the human's soul as a key, they could enter that human's body.
