Demons are a species of dark-supernatural beings. Demons were once human, their souls having been corrupted and warped after spending hundreds of years in Hell being tortured and having all of their humanity burnt out of them. they are left as large, black clouds that generate electromagnetic interference and leave behind a sulfurous residue. Types of Demons Black Eyed Demons - These demons are the most common type of demons, but they are not a homogeneous group. They occupy positions on Earth and in Hell, as they are constantly being deployed and produced throughout Hell. They appear to hold different ranks in demon society and display a range of abilities and powers. They are grouped together because when they possess a human, they can turn the hosts eyes entirely black at will. Crossroads Demons - A Crossroads Demon makes bargains with people, granting a wish in exchange for claiming their life and soul at a later date. Deals are sealed with a kiss. They have red eyes (all except for a black pupil) Special Types of Demons Acheri Demon - In Indian folklore, an acheri is the ghost of a young girl, who at night visits from her mountain to bring illness to children. But Acheri is a Special Demon. Yellow-Eyed Demon Azazel is one of the most powerful demons. White-Eyed Demons Alastair - Alastair is a torturer in Hell Lilith - Lilith is the first demon created by Lucifer. Seven Deadly Sins - In 1589, Peter Binsfeld paired each of the Seven Deadly Sins with a demon, who tempted people by means of the associated sin. According to Binsfeld's Classification of Demons, the pairings are as follows: Lust Gluttony Greed Sloth Wrath Envy Pride (they are Black-eyed demons as well) Samhain - can be known as the "Origin of Halloween". When he reigned on Earth on Halloween night, people kept their children in that night. People wore costumes to hide from him, carved pumpkins to worship him and left sweets at their doors to appease him. Samhain has white irises and black pupils. Demons seem to operate in Hell as a base of operations. Hell was created sometime after Lucifer's rebellion. It is a place where demons are produced. Production of demons depends on human souls that go to Hell and become demons after centuries of torture. Black-eyed demons are constantly being created, and they occupy positions on Earth using meatsuits. Demons usually do not have bodies of their own, except in the case of Acheri Demons, who can "manifest" as human children. Other demons appear as a black smoke in their incorporeal form. Their presence may leave traces of sulfur. They manifest by possessing humans, alive or recently deceased, via Demonic Possession. Human souls can get sent to Hell after making deals or agreements with Crossroads Demons or other demons. Hellhounds hunt and then kill humans who made a demonic agreement and then the human's soul is sent to Hell.
