An evil demon taking the form of a young man
Rotem has a very cool and relaxed personality. He likes spending time with humans, but only because he likes messing with them. He's had a few short romances in his pretend human life, but he's never grown an emotional attachment to any of them.
Rotem is also very smart and calculating (a naturally strong talent in century-old demons whose profession is in the manipulation of others). He's not even the least bit gullible.
When he has to fight, daggers are his weapons of choice.
His physical strength is greater than that of an average human, but about equal to that of an average demon. He also has the ability to cast fireballs from his fists and lightning from his finger tips.
Rotem is still very young for a demon, but in human years he's several hundreds of years old. There's not much to tell about his upbringing in Hell. He was born to two fairly powerful demons who were unique in that they were fond enough of one another to stay together throughout his whole childhood. However, his mother was murdered by another demon who was jealous for her, and she lacked the energy to return to life and moved on to the Lake of Fire.
Now Rotem makes the manipulation of humans, in the favor of Beelzebub, a full time profession. He rarely ever kills a human, mostly because much more damage can often be done by keeping someone alive.
Roger Plum is the alias he often goes by in the human world.
