I’m sure we’ve all seen the old 5D dungeon post on reddit, this isn’t quite that and its use of 4D space is rather simplistic being a basic translation through 3 slices of an un-rotated 4D cube, however its already set up and ready to go.
I hope some DMs out there get some use out of it wether that be for a confusingly long dungeon crawl or just a one session gimmick.
I love running non-euclidean geometries in dungeons – particularly lairs for mad wizards. I often take inspiration from Escher with stairs that go up forever or similar.
My favourite was a hallway with large doors on either end and a bunch of side doors. If you exited out the large doors, you’d seemingly enter a new identical hallway. Except it was the same hallway in a different timeframe. The contents of the side doors shifted over time. Potted plants would change size as a visual cue, etc.
