'Well, we know he can't be a dwarf, halfling, or gnome because otherwise the height isn't right for that torn cloth to get where it was...That won't help me narrow it down much though.'
"Hmmmm...I don't think that will help, unless we're very lucky. Remember when I said he was changing his face? Well, this spooks a lot of people out--spooked me out too when I first found out because it's pretty terrifying to think about one of them killing you and replacing you or something--but he's a Changeling, though I'm sure he never told anyone that once he made it to Sharn. He liked big burly forms rather than the lithe agile ones, but not dwarves. However, unfortunately, I'm sure that that description fits many of the human, half-orc, and goblinoid longshoremen in your guild. Too bad you didn't know him off the bat--I'll just have to take a look for him myself then. Thanks for trying!"
