Escape
The whaterdhavian creatures will be attacked by some weak goblins, lead by an elite goblin. be sure to attack the elite goblin first, while pavel cleans up the weak goblins running towards you, otherwise fenthick and desther will kill him. The creatures will escape however, no matter what you do.
Fenthick
After killing the goblins, speak to Fenthick, a dialogue between him and Desther will take place, after wich Desther leaves. Speak to Fenthick again, and agree to meet him within the Hall of Justice within the week. (you can try to decline, but Fenthick offers you the choice of either going to jail or help him, what happened to Tyr being a good god and all ?)
Pavel
After you kill the creatures, pavel will come up to you and says he's not cut out to be a hero. no matter what you tell him, he will leave your party for good.
End of Prelude
Exit the door that Desther and Fenthick left through to initiate a cutscene, and Continue to Chapter 1.
