Canaan Clay. A young man, around twenty who used to live in a system of families that one who knew better might call a cult. When he was young, social services removed him from this group he had lived with. To him, he had been left behind, a lamb lost from the flock. This spurred into a struggling secondary education where he was ostracised by his peers, preferring the company of animals and things that wouldn't yell at him for writing his threes backwards. He did however become close friends with a young teacher there - but they lost contact after a falling out. In his early adult years, he suffered an "accident", where he was caught in the headlights of a car. He never really recovered fully from it and for a long time was addicted to codeine.
In an effort to rekindle something lost to him, he ventured on a hippy trail that led through Chernarus at the worst possible time. His group all died, leaving him alone again. He found again that there wasn't very much worth living for. After deciding whether to live or die, he saw that some people had found a not-so-happy medium. Zombies. He fell to what was familiar to him. Thousands-year-old stories. An ascetic lifestyle. He had read once, that between two extremes lies what some would consider more valuable than a loaded gun at the end of the world. Virtue.
Canaan wants to find his virtue. Between acedia and an oily charisma is something he'd like to find. By fate, maybe, he was looking for Canaan. A promised land, not really here or there. It was found through travel, a journey or rhila. Canaan would welcome many to his flock on this path through the flood. He isn't a Caesar looking to cross a Rubicon, a Moses making miracles, or a Koresh fitting to become a god in his own image. He is Canaan Clay. Looking for olive branches after a something short of a revelation.
Non-RP Explanation: I should preface this with stating that his goal isn't to create a crazy death cult who praises the sun and watches apples. Instead, his own faith is shaken and this fulfilment is a journey of the self. He is far from a zealot and would like to debate religion and philosophy with near anyone. The reference to the addiction is displayed in game with a hoarding of codeine. He isn't a junkie who will hunt people down for this, but does harbour an addiction. As for killing: prefers alternatives, but isn't pacifistic to his death.
