I've been pretty clueless as to that myself for... quite a while, I suppose. It's gotten to the point where I don't even readily remember who was doing what, or even who various characters belongs to (luckily it's easy to check up on, I'm just pointing out that I can't immediately recall a lot of things). I've honestly been contemplating doing a soft reboot of the RP (basically forming a new party of characters but continuing the story in the current worldstate), but it both seems like the "easy" solution and a sub-optimal one.

[I]Sigh.[/I] I suppose we could... I don't know, make some very rough transitions to get the RP to a playable state again? Sort of just going "Aemoten, Thaler and Olan left" (since that was already in the cards), and otherwise, eh... figure out what to do with the remaining characters? I mean, Claw is still off on whichever adventure he's on all on his own, Iridiel and Angora are sort of just there, now playerless (honestly, I'd hate to think how devastating it would be to Jaelnec if he ended up losing Aemoten, Thaler, Olan [I]and[/I] Angora all at once; he hasn't grown quite as attached to Iridiel, but Angora certainly made an impression).
On the bright side we have Domhnall still around (though I suppose he goes wherever Iridiel goes), Jaelnec is determined to complete his quest, and Yanin's group is waiting to join. There's also a few readily available courses of action, even if the group wants to stay in Zerul City for a while; they still have the Sister's of Torment in the city (though I don't think they've heard about that yet?) as well as a couple of other things waiting to be discovered, and the next stop on the journey - Mount Zerul - is all but decided already.

Another effort should be made to recruit new players, but as I said after the last failed attempt, I'm not going to do that unless I know the current players are ready and able to resume at least semi-reliable activity.
Eh... so mostly, I guess my plan would be to handwave stuff that would require input that would be too troublesome/slow to get, and mostly just brute-force the characters into positions that would allow the story to continue as unimpeded as possible.
