Everyone: at this point, there's a few things that I can suggest as next courses of action. PCs can:
* continue role-playing through the celebration. Xana is fleecing Klak of coin, after all.
* attempt to ferret out clues relating to Black (though here's a freebie: each PC has already got the sense from the townsfolk that they've been actively hunting for Black for some time, and have come up with nothing concrete, so they're on quick alert status to respond to any threats, and expect to only get leads indirectly, through seemingly unrelated activity)
* seek out and find class trainers so you'll know where they are later. Note: I was going to introduce each class trainer during this party, but then I realized that not everyone is necessarily going to train in the same class they started in, so I'll let you drive seeking out which class trainers you want to meet. So far, we have seen Cormac (fighter trainer), Diana (cleric trainer), Tuan Vo (monk trainer), Njall (paladin trainer), and Mironund (mystic trainer).
* work on setting up the Dungeon Busters office
* investigate the rumors you've heard about Orlane (which brought you to Hochoch in the first place)
I'm sure you have other ideas.
