I cleaned out the Unseeing Eye Cult and want to go down the hole to the undead kingdom. Unfortunately, nothing seems to work. How do I descend? Note: I foolishly slaughtered all the cult members a long time ago (with no remaining save game from that period), so please let me know if I missed any triggers by killing them (I already know that I can't complete the Kagnaxx quest because I killed the guy with the key).
If you solve that quest by merely slaughtering them all, instead of by getting the two pieces of the rod, you will not be able to go to any of the other areas associated with the Unseeing Eye Quest, i.e. the Undead Town, the Beholder layer there, or to the temple of Amauntor.
