The Sewers

When you take the exit into the sewer, head across the bridge to your right with the steps on it and into a room where you will likely encounter rats, and perhaps a couple of goblins. The room will have a staircase on one side. Go up it.

Follow this path until you reach this spot:



When you try to exit you will have the chance to edit your race, sign, or class. Save at this point several times, so that if you want to start a new game, you will be doing so at a point where you can A) change all your details, and B) not have to go through the beginner's area again.
