Tika receives a royal gift, and the Companions leave Qualinost bound for Pax Tharkas. On their way they find an old battle site, amongst the corpses of goblins and humans they find a survivor, Eben, he joins them. Draconians appear, Tika creates a new form of combat in the aftermath of the fight she kisses Caramon. They resume their journey. Suspicions grow. They reach the outskirts of Pax Tharkas. Head towards the secret entrance. More suspicions. Eben recommends a frontal assault on the fortress. The party is followed. They enter the secret passage. Goldmoon and Caramon have “The Talk.” They search for hidden doors only to find a giant slug. The follower is revealed. Tanis receives a royal gift. The Companions have to take another path.

It can be a little confusing when we're talking about the Sla-Mori and which paths they took when and where the giant slug came from, etc. I thought this map from the Dragonlance Atlas would help. The Companions camped at the first intersection after the Secret Entrance. Raistlin felt the evil come from the western tunnel. The door that the slug came out of is opposite (west) of Kith-Kanan's throne.
