He is on Coalition of Tradesfolk Underground faction. You can raise this faction easily by doing the first steps of the Rogue Errands quest. Just get as many of the bent playing cards as you can carry (they're not lore) and hand them in to the dark elf outside Qeynos. Drop or destroy the note you get back from this step. The only negative faction hit you'll get is for Ring of Scale, which is the Kunark dragons like Gorenaire, Talendor, etc., and some mobs in Skyfire and other areas.
Edit: Bah, mispelled his name in the subject. Oh, well, you know who I'm talking about! =)
