Ser Constantine cannot remember what his real name is anymore. Its been too long. The Gimmick started as a joke he sometimes remembers, but he is never sure of it. All he knows now is the title. A man once but now a protector of the innocent and a slayer of those who would oppose his lords justice or his gods might. Ser Constantine is in search of redemption for a crime he can no longer remember. He needs above all else a royal pardon and for his title to bear weight to anyone who knows it. Constantine will do whatever it takes to remember what he locked away behind a blunt force trauma or perhaps a river of intoxicants, and to secure his right to a hold fast as one Lord Constantine under the right of the True royalty in the realm of Chernarus. But to accomplish this he must first find someone truly worthy of rule to establish their righteous empire.
Ser Constantine is aware that Chernarus is not truly a mid evil realm of fantasy but having locked away any psychological trauma his past identity and the actions accompanying it, he instead is obsessively determined to make his identity one that can function in this world. He also believes that to unite Chernarus under a royal banner would be good for the lands and the people as they would be under protection under the king/Queen and justice would have a high place in the land.
Ser Constantine is an old man for a survivor of the infection. He is in his mid to late 50's but suffers no terrible debilitations. He speaks with an English accent but he can't tell if it was his to begin with or another part of his character. While he is unaware of his life before a little while into the infection he has made little attempt to discover what his past was, apart from a few guesses at his profession. While not quite Jason Borne he finds he is basically familiar with fire arms and physically capable of a lot for his age but his mind is not sharpened to combat or survival but instead the arts and contemplation, prompting him to believe he might have been a Professor or a Doctor of some sort on a relief effort on behalf of some institution, on account of the clear aptitude for higher learning/understanding.
