You're the GM, you decide, haha ... but if you feel that way, I figure the species of the thief isn't as important as what he stole or maybe it's just important it's a rookie mission for your character. ^.^

Well, it and the other two starter missions are supposed to just be basic missions for us to break the ice with.
That, and I was planning on saying that the thief stole it for a community of non-passing otherkin and half-bloods that live in the sewers. So it's more important that he stole it for the community, and what the community wanted it for, than that he is something in particular.

Edit: Added some lore to the interest check.
