Modular Dungeon project, map#1, room#1

I'm trying to start a collaborative dungeon project and this is the first room!

It's an irregular cavern, smaller than 20x20 feet. The floors of the chamber and the tunnel leading to it are muddy, with the mud extending up much the walls. In the southwest, there's a narrow crevasse that opens both up and down, through which air travels. There is a 1/6 chance at any given time that some strange smell is carried on the air.

The center of the muddy floor is hardened by the passage of bare feet and the perimeter and walls are covered in strangely colored bunches of mushroom caps growing on fat stems.

The goblin mushroom gardener who lives here can see in the dark, move more or less silently, is armed with a rusty iron fillet knife, and carries two random potions that she's made from her crops. She might use those potions if someone intrudes with violent intent, but she might also sell them -- she's saving up to buy a mate and start her own line.
