Lich Hunt

The idea here is to have a lich take over a school of magic - this you get battles against novice magic users, plus the lich and his henchmen. If this is something like a university, you could also have bands of clerics or monks associated with the rest.

Being undead, the Lich would also be protected by swarms of undead.

Plan - would be for multiple people to work up pieces of the adventure. Some of the pieces you need are:
- encounters with the magicians
- the battle with the Big Bad Lich himself
- possibly a battle with a gang of clerics or similar types
- lots of undead
- encounters outside, on the approach
- random encounters with monsters who use the opportunities created by the lich and his works.

Doing this as a team effort has a lot of advantages - from the obvious division of labor to the way it lets parts of the dungeon contain surprises.

We need to work out a backstory and setup. We need to work out a way into the adventure.
