Halloween progress

I've been extremely busy with work the last few weeks, but I've been trying to continue to work on my contribution for the NWN2 Halloween 2008 Event, sponsored by bouncyRock Entertainment. Things have finally simmered down a bit, so I was able to make some progress. Here's the concept:

Vendalus has invited an eccentric group of old friends to celebrate The Day of the Dead, renovating a local manor into a house of horrors for the cities’ social elite. Most of the guests have gone all out for this event, spending impressive amounts of gold on various magical illusions to arrive in the guise of demons, devils and the walking dead. But beneath the air of sophisticated revelry, old grudges are preparing to surface and someone is plotting murder. Stepping innocently into this gathering, our hero is the best hope of bringing the culprit to justice. Can the players help Vendalus figure out who the assassin is before killer escapes?

Here are some screens of the main suspects:

The main interior has been built and I'm down to just moving minor objects around. I've got a good sense of the major plot lines and most of the suspects have solid motives and history with the other guests. The two big things on my list are the opening conversation/cutscene and the conversations with the guests leading up to the big reveal. I'm a little worried that I'll get it all done by the 13th, but I'm trying to stay optimistic. Suggestions are welcome!
