It is a dusty rune. That should have been their first clue that it was dangerous.
"That is one really big door"
An elaborately worked door, carefully made to balance upright on a horizontal bar, containing a deadly trap.
As traps, obviously there are the standard protection glyphs which engulf you in fire or freeze you when you try to open locks. And then there are the non-standard ones…
The unwitting players tromping through the swamp won’t know what hit them.
Ettercaps (the spindly evil woodfolk) are always good for traps: their pine woods are so dense it’s difficult to see what’s a trap, what’s a branch and what’s an ettercap…
Dungeons, should make sense, in an ecological way. However, to have life, you need to have a physical place to use them. This expands upon the ecological dungeon, giving it a framework to exist in.
We have all seen articles on how Dungeons don’t work. I’ve seen such articles before. But this time, an idea struck me: Why not do a dungeon that really works? Where creatures live their lives in harmony; just the right ecological way?

(Figure there has been a whole historical epoch or two since then) There might be a hidden tomb or something somewhere in the lands, but it is unlikely. This does not stop people from selling maps to them all the time.
