The walkthrough I've been using says that after killing Balthazar I can go back into town and visit the temple, go to Watcher's Keep, etc. I'd like to do that, but I can't find a way to exit the monastery area except by going to the pocket plane, and I can't get to Amkethran from there. I came in from Cave of the Dead, but the way back to there is sealed. I can go out the front exit into the courtyard area, but haven't found a way from there to the rest of the town. If I click on the main gate, or the entrance to the cave, the party tries to walk around to the side facing the town, which of course it can't do.

What am I missing?
