i don't know what order people take the quests in, but the first few times i played going to spellhold/underdark was only after every topside quest was done, meaning that the party was pretty beefy.
so an imp tells you to flee the city once the matron is dead. hahahaha. why on earth would you run away now? the two most powerful people just died to a demon right in front of you. more than likely you've also already killed Qilue (for the aboleth, though you can browbeat it into not making you kill her). you've also done the Jarlaxl/Deimos quest and wiped out House Jaerlat [sp]. guess what? there's nothing left in the city but a few minor spellcasters (both slave merchants are), some fighters, and slaves! wipe the whole damn city out!
for a grey elf like myself, this was my favorite accomplishment.
and if this has already been discussed, excuse my ignorance
