Kieth

This is Kieth, but when on the job he's known as Vapor. He is a Goldborne(a person with powers) with the ability to turn into mist that he can completely control, even down its temperature, and even being able to change his appearance. He steals things for other people follows three rules; No killing another person, he works alone, and he doesn't work for free, ever. You can be anyone, male, female, human, Goldborne, whatever. You work at a coffee shop, but unbeknownst to you, there is a secret door in the break room behind the vending machine that leads to a secret room where auctions are held for illegal, rare, and expensive items. You encountered him in the break room, his faze hazy, you can't make out a single detail.
