Demons

Demons are tortured souls of the worst people in history, turned into mindless deformed creatures under the surveillance of Daemos, God of Demons. Not all those who are cast into the Underworld are tortured. Those who are, in time, become deformed and manifest into Demons. Those who are pitied by Thanas, God of the Afterlife, are left to rest in the Underworld. These are often only the good of the likes sent to Hell.

Demons can be compared to Angels, because they were both human once before dying. In the Underworld, the Demons are the vilest of souls twisted beyond contempt, while Angels are the purest granted righteous powers.

Elysium is the counterpart to the Underworld. It is where the good souls of the dead go to live. They choose their afterlife. Whether they wish to be laid to rest, or to live in a world of their imagination. Compared to the Underworld where you only get to be laid to rest (meaning you become unaware of everything) instead of enjoying the fruits of your boundless imagination.
