More ideas!
-A doorway to something that looks deceptively like the Infinite Staircase. This is actually some form of living creature who was imprisoned, and the farther the characters travel, the more likely they are to be eaten...
-A creature camouflaged in razorvine: when the PCs want a snack, it jumps out and attacks!
-A defunct planar model, unused for centuries or more. It can be used to accurately track one thing wherever it is in the multiverse of the player's choice, but they have to deal with its guardian first...
-A broken statue of the Lady of Pain, words in Primordial scratched on the base. Any number of encounters could happen here!
-A meteor strikes the maze not a mile from the players! Do they go towards it or away? What mysteries does it hold?
I can feel myself running out of good ideas. I'll quite while I'm ahead. Still good, or do you need something different?
