Hi! That's a Tool Vendor. :) There are 2 in all of Ur. The other is at Cebarkul. Selling items to one of the tool vendors will give you a better payout vs. selling to other vendors.
He's sooooo trippy looking. I really wasn't sure what to make of a lizard wearing a tribal mask. More power to him, I suppose. Thank you for the hint on the tool vendors!
