12. NORTH GHOUL TUNNEL
This tunnel is roughly 4ft. high (and narrows to a similar width in places), and looks to have been dug out by some kind of burrowing creature perhaps.
The whole place has a faint smell of decay and rot.
ENCOUNTER: Any ghoul encountered within this dungeon will likely use this (and the other tunnels) to flee from, or ambush the party (should the opportunity arise).
Note to self: In another room, goblins will be attempting to hold back a couple of ghouls – while one or two other ghouls use these tunnels to outflank them (possibly running into the PCs along the way).
ADDITIONAL NOTE: As you can see, I'm starting to flesh out a bit more of the dungeon map as I go along - just to get a clearer picture of where I (might) want to go with this.
