Fenrir

a quick rundown of his story is he's a dragon demihuman artificially created by solaris along with his sibling, but when they're around 10, he and his sibling make an escape plan, and his sibling ends up having to "sacrifice" themself to make sure he escapes (though they're probably not actually dead), and he ends up wandering until he's found near dead by a couple in nisan who adopt him and end up naming him since he was only regarded as an experiment and not a person (haven't decided on a name yet, though I might just name him fenrir after myself!) once he's around 18 or 19 years old, he starts remembering more about his past, and becomes terrified of the fact that he was created to be a powerful and destructive weapon, and becomes afraid he might lose control and kill his family or the village as a whole, and ends up running away, once again found near death, but this time in the desert by the yggdrasil crew (a bunch of pirates), and while there he ends up very close with and even falling in love with bartholomew fatima, though by the time the game starts he hasn't gotten the courage to confess yet! he's obviously very distrustful of anyone with any affiliations with solaris, like elly and citan, and even sigurd. he's generally a kind person and tries to act playful and happy, but obviously has a lot of issues and is truly sad and scared a lot even if he doesn't show it.... he has very strong morals and will always fight for what he believes is right, and vehemently hates anyone he sees as cruel. someday he wants to return to solaris and get revenge for what they did to him and his sibling and every other experiment they created, though unfortunately for him it may possibly end with his sibling having been fully turned into a living weapon and he might have to mercy kill them...
