The Lost Halls (2017)

Food for the GM's Mind

From the introduction:

Does the dungeon make sense?

Well... not really. But in the same way it kind of does.

There are some halflings in the dungeon, a halfling cabin. Two or three planar portals, depending on how you look at them, It’s implied that the original owner was a Lich, but he’s not longer around. There is however am undersized Beholder. I get a general theme of a forgotten dungeon that fell into oblivion and was later retaken by the undersized beholder, who is actually a coward and uses illusions to trick visitors and later eat them.

So take this information into account when judging this dungeon, it was created by more than twenty five people who don’t know each other and simply collaborated with a room each. You are of course free to repurpose the illustrations and map, or to adjust the rooms’ contents to whatever thing is more appropriate for your game.
