I'm really sorry Milo and eveyone that was on the quest. For no particular reason NWN crashed twice for me and I had to restart it, then my PC crashed three more times and reboots are not quick this my old clunker so on the third crash I've given up.
What I hope happened, was all the explosives were set and my Pseudodragon set the lair on fire (to ignite the explosives). I'd have unsummoned him and teleported out, however since I wasn't there I guess I won't know. I'll pick up any reward that was given out later, and I can make it out on my own. Thanks for the killer time Milo!
(As of this point my PC won't start up so... yeah... couldn't get back even if I had the will to try again)
