In the catacombs you'll meet many monsters. You'll think you meet Gorian, Elminster, and Tethtoril but they are merely dopplegangers like the rest. You'll then meet Bor, Prat, Sakul, and Tam who are waiting for Saverok. Fight them, and the spiders on the left and right. There are basilisks below you. Finally you meet Diarmid who gives you more info. Head on out.

That's it, you're now on to Chapter 7.
