Name: Atreus.
Alias(es): The Lord of the Unknown.

History: He was allied with Praetorious back when both were still mostly human, but betrayed him in a quest for power. He is now a shady figure who mostly observes and controls situations through minute applications of force.
Appearance: Atreus resembles in many ways a 19th century aristocrat. He wears a black suit, complete with coattails and top hat. He appears to be in his later 40s, with straight grey hair.
Personality: Calm and collected, Atreus is used to being in control, and usually is. He is ruthless and has a disregard for the lives of those around him.
Objects: It varies.
Weapons: His unique abilities.
Abilities: Atreus possesses the Holder-like power to manipulate the laws of nature around him and control his environment. The longer he occupies a space, the more malleable it becomes to him, and the more he is able to control it.
Other: So, yeah. Atreus probably won't do a whole lot, mostly just meddle in people's affairs and generally be an asshole. Fun stuff.
