The NPC that creeps me out the most is the guy standing near Roarich in Ul'dah... His name is Wracwulf.
I do my Goldsmithing leves there and the sudden random fitting while I'm synthing freaks me out lol.

(Ok, when you speak to him he says: "Bloody shopkeep thinks just because he has coin he can push good people around.
I've half a mind to slice his throat and show the bastard his blood runs red as mine!", which is probably why he's acting angry... but it's still weird.)
