Sorry I haven’t posted in a while, but we’ve now reached a new phase of the game.
I have no direction to point you guys in. I know what happened to you (and the kingdom), but it’s up to you to find clues and evidence. If you come up with reasonable ideas, I’ll be sure to give out appropriate clues as they come up. But I haven’t planned anything like “If you find the magic key in the Castle Arrrrrghhh, then take it to the dragon’s lair, then open the third door on the right, you’ll find the treasure.”
I see two options right now. One, stay in the keep, and two, go somewhere. You might come up with a third option that I haven’t thought of. The only reason to stay that I can think of is to ask Chimin or Myrtis more questions. The only place that you’ve come up with to visit is Caleme, seat of the Archbishop. You could also go to Kobing, but that’s pretty far. You could go to Conwan’s keep. You could go to Tashal, the big city. You could go to Olokand, traditional summer home of the king. Or you could go to any other place you desire.
But pretty much no matter where you go, I’ll make sure that stuff happens to you. Hopefully, some of it will be good. 
Here’s a thought that I had: Being that there is no postal service, men of wealth often hire messengers to run letters between strongholds. If you could find out what messengers have been in and out of certain places, you might get an idea of who has been talking to whom. Of course, the messengers might be pretty tight-lipped.
