OK, I blew the crap out of Adrianna and her cronies, but I thought she was suppose to drop a key. I've looked over every inch of the room and found nothing. I did get the bone key and made it into see the old G'Eeser, but cannot go any further. I found an elevator with a lock but no key that I have will work. I'm sure that I'm missing something but not sure what it is. Can anyone help me. Gawd, I need it!!!!!!!

You're in Skull Castle, aren't you??

The lich should have given you a key that gave you access to the areas under the main castle. Did you get a key from the Lich?? If you did get a key from the lich - you need to go (from the entrance) to your right, down the stairs and in the middle of the room you enter there should be a grate to the south. The lich key opens that area and gives you much more to explore.
Is the elevator the elevator in the maze area? The key for that area should be closeby, actually.
If none of this is helpful, perhaps you better give me a better description of where you are now!
Have Fun!

Adrianna will not drop a key, only give you one after you've finished her quest. This key is (quite) non-essential, because it only opens a lvl12 lock with a treasure chest behind it. The lock you can even get open with bashing (strong character), with very high traps and locks skill, or with good lockpicks.
Killing her will have no impact on completing Skull castle.

But you did miss out on the Vampire ring by blowing her away too soon (and the neat little action scene where she tries to use the scroll of binding - heh heh). Hope you don't have a vampire in your party, because you will really miss that ring.
