I'm swamped writing, so this is a simple post. I drew this map several months ago. For various reasons I dropped the project it was associated with. You might find it useful, so I am adding it to the Interesting Places series. There's no interesting history for you this time. This is simply a dungeon area that wants to be keyed and explored.
This map is called "The Junction" because it connects various parts of a larger dungeon complex together. This would be a good place for some competing factions to come together for a fight. Alternately, this might be the 'back route' through a humanoid controlled area, so sneaking might be the order of the day. It's really up to you to decide what the nature of this place is. Figuring out where all those off-shoots lead should be terrifically fun.
There's no legend for this map, but it should be fairly easy to read. Here's a list of things visible: stalagmites (with x's), stalactites (with dots), stairs up, stairs down, doors, double doors, secret doors, secret trapdoors, subfloor passages, rubble, statues, columns, circular pits, water, terraces, burial niches with skeletal remains, and sinkholes. Oh yeah, I almost forgot the brazier in the room with the secret trapdoor. That's it. (By the way, those aren't false or one-way doors in front of the rubble—those are actual doors, but they are fully blocked by the rubble.)
