1.A large cavern filled with stalagmites rising from the floor. The south and east sides of the cavern are choked with the stalagmites requiring anyone trying to get past them to squirm and wiggle past them. The east side opens into a tall chamber. The south side has a hidden passage that leads to a ledge in another cavern. The west side opens into another cave down a slope of loose rubble.
Ogres throw their kills up here, at least five partially eaten villagers, three horses, and two sheep lie rotting up here. A magical bow has been deposited here as well.
Gas: The gas is a green substance that is heavier than air. It is poisonous to breath and fire will not burn in it. Gas masks and flashlights are necessary to travel through it.
Poison: reroll attack whenever not poisoned in a poisoned area.
Mushrooms: If the mushrooms are hit with enough force, say by an attack with a weapon or a firing dart trap they explode violently into spores. The spores then root themselves and will grow into giant mushrooms in the future. The explosion is dangerous enough to do damage.
Anyone with spores attached to them may find mushrooms growing on them if left in armor or touching skin for too long.
2.A huge cavern with an eastern slope of rubble that raises to another cave, to the south are two different huge passages. The western one leads outside into a steep valley. The eastern one opens into another large cave. Green mushrooms with red spots grow around the cave.
Two ogres sleep here. If a fight goes on too long a third ogre shows up from the exit. The chamber is filled with poisonous gas.
3.A large cavern with a small rim on the north side. The rim can be accessed by a small passage from a cavern above. There is a tiny cave in the rim with a goblin cache with several magical items.
An ogre shaman has an altar in this cave grown around with mushrooms. The room is filled with poisonous gas. The rim is just high enough to be outside the gas.
4.A long cavernous tunnel. Half way it intersects a dungeon cavern. The north side passage has a flight of stairs. The south passage ends in a “T” but both sides are filled in with fallen rubble. The tunnel connects to a large cave on the west end and the east end breaks into a dungeon passage.
The floor is curved inwards and several green red spotted mushrooms.
