Tim is the barkeep of the Rivertown Tavern and is located on the first floor there. He gives the quest Band of Brutes. You can mind read for 40 exp to learn where he hides his stash of gold that contains 200 gold.

You can buy Food and Drinks from him.

It seems Tim thinks he is an author. In a room on the third story of the tavern is a Strange Volume I. It gives a hint to another (in the first floor, close to the bartender), which again gives you a hint to the other (in the second floor, on top of a pile of books). The third book gives yet another hint to "the real story".

The series of books ultimately lead to a skill book cleverly located behind the logs in the tavern fireplace.
