Megadungeon for the holidays

So I hope to run a bit of a one off dungeon crawl, perhaps making it an annual event in a megadungeon of my creation.

I have a messy overview map and started on some of the levels. So as to not reveal spoilers for the Day after Thanksgiving dungeon crawl, I will keep no notations, but here are the maps I have so far.

The upper left is a burial site. The next four are layers around a central mining shaft.

The upper left is the ruins of a wizards tower, then its basement and caves. Then some other caves deeper down. The Right side is a vertical dungeon for flying creatures that have many niches in the shafts.

More to come.
