Part 1 of a 2-portrait commission I got from https://www.furaffinity.net/user/akidaswolf, of two of the characters I run for a friend's DnD campaign. Our DM has grafted in a few different sets of rules, so it's not all perfectly canon. =P
Queek is a Skaven (rat-man) assassin of Clan Eshin, who decided to set aside the rat-race, and strike it out on his own. In short, he wound up in the current campaign. Queek runs the local assassin's guild, which barters quite richly in the life and death of individuals. These contracts attract enough business to the town of New Phalen (coupled with the business conducted at a neighboring wizard's tower) that the law is quite willing to put up with him. That, and despite still being fervently loyal to Clan Eshin, he has taken an oath of citizenship, and thus, serves the Empire when called upon. It's said that if you ever see his face, your time is up. In reality (the way I roll), Queek is rather bumbling for an assassin, but he can usually pool his resources (i.e. pawn the job off on his students) to get the job done.
