Various Random Dungeon/Area Ideas

[:1]This is a collection for ideas for the randomly spawning areas and dungeons.

The following an example of my idea (assuming there are sand maggot-like monsters). You are exploring Sundered Pass, when you come across a hole in the ground. You enter and discover the place is an underground nest for the sand maggots. You can see eggs along the walls, and the nesting hollows, etc. After exploring the area, at the end there is a gold chest (or the equivalent).

The main idea is, create some areas that are specific for one monster type that takes advantage of the higher graphics than Diablo II had. A sand maggot nest, a dark cultic camp (like what Abd al-Hazir watched and noted in entry 42), whatever the imagination can think of.
