Quest tool: I'll do that, thanks
Zhentil Keep: The Elminster encounter near the entrance sets quest 2 to 2 (this was the second of 2 that do so, the other being Dragongate Keep). Once I found that, I used it to resolve my problem here (since there was no going back to Dragongate Keep at this point in the game). I read in another post where you said that was an unintentional encounter, but it was useful in this case so I didn't have to modify the design or hack my character file or anything like that.
Continuing: Yes, so far so good, thank you. I've hit a lot of new encounters, Jerren assigned the Yulash quest, etc.
