Green skin, beady eyes, wiry black hair, short - yep, that's a goblin alright. A reasonably fashionable and well-dressed goblin, to be sure, but a goblin. He's usually wearing a slick grin, eyeing up others around him.

While overall gregarious and seemingly friendly even to strangers, he also seems to be the type that would be found selling used carriages. Or whatever else he can sell, for that matter. He'll happily procure whatever it is you want, if you're willing to meet his price.

Race - Goblin (Azeroth/Warcraft)
Gender - Male
Height - Just barely over 4'/1.4m or so (on the tall side for a goblin)
Weight - Wiry build, quick but not terribly bulky
Profession - Businessgoblin, Trader, Rogue, Warlock, Engineer, and anything he thinks seems profitable at the time

Goblin Traffic Signaling:

White - Roleplay, Interesting/Developed Characters (such as with descriptions, background, not just two-dimensional etc), Taking advantage of people, Voyeurism (Overt or Hidden), Shady Dealings (Morality is for suckers and the poor), Summoning and/or Dealing with Planar types, Making Money/Getting Rich, Ganging up on someone, with a group of goblins especially, but anyone that makes sense.
Green - Most races, of human size or smaller. Tell/OOC friendly.
Yellow - Very Large women in ERP, such as 8' tall or more.
Red - Poop, Gore/Gory Mutilation, body horror, things being pushed inside him. (If you want revenge for something he did to you, just kill him, or better yet, take his money, he hates that more than dying).
