All sorts of nasties, lol.
some doom knights, and doom knight commanders, demi liches, spectres. All sorts of things, that even a 40th level party of three would have a hard time dealing with.
We did it, because there were a few players that wanted to lay claim to the tower as their own, and rather than have a war in Palanthus, a few tower mages released the evil from the grove itself into the entire NE section, but contained there, lol.
I am currently working on, among other things, setting things up to open the tower. I am looking into building the inside of the cursed tower, and then having an adventure to clear it, and occupy it. Either a single mage, or as a haven for the tower magi. Something is in the works, but the process is slow, because of other things. Thats where it stands right now though.
