Krynn's Vanguard continued to clear out the floor coming across a puzzle of locked doors that had three circular indents in it. They eventually learned that it was unlocked by inserting three signet rings into the doors. The only issue was finding said signet rings.
Exploring more, they actually met a Succubus who, surprisingly, wasn't interested in fighting, nor seducing any of them. Instead, she was going to hide out here for a while before she could sneak away and get back to her own tasks from whence she came. She did reveal to the party that all the monsters and demons were here on the orders of the Prince of Demons. A name they hadn't heard before. Perhaps they'd learn more talking to some of the demons. Unlikely, but worth a shot.
Krynn's Vanguard cleaned up this floor and found a spot that was enough out of the way, not too bloody, and didn't contain many dead dwarf remains to rest for the night before continuing on.
