well, i mean, there are only so many places he could have gone - your first (and to be fair, only) hint is the dead magisters on the west part of driftwood (provided you hadn't already killed them). at that point, it's just a matter of looking in that general direction
So many places he coiuld've gone??!
Sometimes the problem with the forum is it's hard to tell if someone is making a joke. Let's see, so after leaving Mordus's house, how many places can I look? Exactly the ENTIRE MAP.
What about some dead magisters in Cloisterwood is supposed to tell me anything about that Lich? What's the connection? Do you understand the issue here? There is NOTHING in the quest log, and nothing in the conversation with the Lich, that gives me any clue as to what the Lich will do next, or where. I could easily have found him somewhere in the Black Pits or Bloodmoon island. So, other than randomly stumbling upon that area in Cloisterwood, there's nothing to point me that way..
