A basic personality was written but isn't concrete in any shape or form; will be changed as he develops organically through game play.

Precise and calculating, Osiris is unintentionally like his father the deceiver, much to his adoptive mother's dismay. Her lessons in etiquette sunk in, but, instead of making him the epitome of what a true gentleman should inherently be it has, instead, given him a weapon in his arsenal. His cruelty is not done intentionally but he is a domineering creature, vigilant and cold. The Deciever had spent much time undoing Athena's work and making the boy into his own image, carefully and patiently crafting a misguided righteousness that is born of the harsh guidance and secrets. Osiris is commanding and not unlike the deity he is named for: a judge. He believes that he stands for justice but he is blinded by the lies and whispers Setekh filled his at the time young and impressionable mind with. He is soft spoken, and always assessing and observing. He has an eidetic memory which, while extremely useful, also means he tends to get bored if he isn't continuously stimulated mentally — and given his passive aggressive tendencies this is not a good thing for him to be. Also, he's manipulative and will more than likely take advantage of situations if he can find a way to do so. This was not the kind of man Athena had raised him to be but was driven too by the encouragement of a patient madman his biological father and by the grief that struck and has festered in his heart upon learning that Athena had been murdered in a fire (that had killed most of his adopted family as well).
