FYI: some of you may know already from other games, but JoshuaMabry has made the hard decision to step away from Gamers Plane, due to new work and life commitments. Coincidentally, the party's rogue, Joseph, is unconscious but stable at 0 HP.
There's a couple of questions this raises: the short-term and the longer-term.
In the short term: if you as the party want to revive Joseph, Albertus can use an application of his healer's kit and Joseph will roll his hit die (if he hasn't already today) and I will run him as an NPC as you explore the rest of the Ruins for information that could help revive Devek (and maybe treasure, though the party has been pretty content to let the treasure go so far). If you don't revive Joseph, you'll have an all-player party, but no rogue. Which is OK.
In the longer term: Do you want to continue as a 6 PC party, or should I open the game up to new PCs when the party has returned to Hochoch and resolved the Jarls' problem? 6 PCs is plenty for now, but probably the minimum for surviving later parts of this classic AD&D adventure. I certainly would want to get more PCs if the number ever drops below 6. We don't have to answer this question right away, of course, but I wanted to start you thinking about whether you will want to invite more people when we get to that point.
