Gem is a... Well, what he is isn't terribly important.
Gem has no one name, never giving out what he perceives to be his name, instead going by an alias that changes if he ever gets caught.
His most recent alias has a thing for gems, to the point where he actually wears contact lenses made of solid crystal.
Tends to like shiny objects.
He steals from corrupt authority and people he deems could live without, and returns Wealth to the poor and needy. In gifting, he's as unknown as in his thievery, leaving things in people's houses, mostly gems he had cut after he "obtained" them to make sure they wouldn't incriminate the person he gave them to.
Genrally, gem dislikes violence, but is still quite good at it, and his horrid, serrated teeth help. His aim is nearly impeccable, never hitting very "hard" but always hitting the right spot.
Gem is an amazing liar, and almost never gets caught... As most people would believe him if he told them their shirt was secretly an evil magic object bent on world domination.... At least, as long as it wasn't true.
Gem is quite talented at alchemy, but thanks to his recent "capture" he lacks his alchemy kit.
Dispite all this, his loyalty is fairly astounding- once he grows to like someone, his conviction is unwavering.
Gem worships desna's shadow, the black butterfly, and goes out of his way to aid the blind and the deaf, along with performing her daily obedience of undetected charity every day.
Suiting, in a way, as he's able to turn into a moth.
