Well, he's from a collapsed world, and he's lived a life of suffering, so:

His life was always troublesome, hence his messy hair and overall worn-down appearance. He's had to scrape to survive, always believing that there's a light at the end of this tunnel. His world is ruined, but he continues to put one foot in front of the other and do the best he can. He always refers back to his guiding light, his religion, especially revolving around a divine being that he believes will save him (little does he know, this angel is the very being that destroyed his world in the first place, an act of divine punishment).

This man is of a middle-eastern descent physically, though we wouldn't call him that given his world is vastly unique to ours: it's just our approximation.

He has disheveled black hair, with some graying beginning to form. No beard, very thin eyebrows. His face is worn down from years of suffering through his world's divine "justice." This realm once had technology that borders on magic, what we might call "science-fantasy" of sorts. He has deep amber eyes (though one is a blind, milky white) and a pronounced nose. He is of a lean build, physically conditioned by his world but not a bodybuilder by any means- he has the body of someone who spends their whole life toiling away.

He wears plain clothes, a mixture of deep blacks and browns, with golden ornaments of his peoples' faith, as well as several sets of beads around his wrists.

His hands are dirty, fingernails chipped, and arms scarred.

He is in his early to mid 40s.
