You are the Merchant NPC (http://goo.gl/oEWAu). You sell token-purchasable items, things like weapon/armor enchantments, emergency potions, and (far in the future) running the auction-house. Send us your photo, and that NPC will have your face & hair, your name as a tooltip, and clicking your avatar will bring up your profile (with badges, website, blurb, etc). 500 tokens, Name in the Hall of Donors & wiki, backer-only full-set, and t-shirt. (See above for info). Our utmost gratitude!
