While starting to explore level 10, the party runs into a huge wave of undead. Luckily, Rizwynn was there to save the day. Finding a couple of statues they can teleport between, they find themselves in drow territory. Surprisingly, rather than attack on sight, the drow on guard welcomed the group with an offer to meet the lady in charge, who had offered guest rights to everyone on that level. When they meet her, she offers to let the party pass in peace, if they kill or otherwise dispose of Muiral, one of Halaster's apprentices who now runs rampant over the northern part of the ancient drow stronghold. The party agrees.
