I'm actually working on a Half-Dark Elf (Or Half-Dusk Elf as his canon would call him), who'd both ways totally fit into this universe and not fit in. How would you feel about cross-dimensional shenanigans bringing him to this world? If not, I might be able to try adapting him to the setting, but there's certain things that are integral to his character that might have be altered or outright gotten rid of.
