Labyrinth Key

This is some kind of strange and intricate device made entirely of stone. It seems to depict a large maze carved into a miniaturized mountain range. As you examine the small device, minuscule floors of the complex maze slowly shift and move around creating an infinitely more incomprehensible maze. Some hunters have discovered a relief in the deepest depths of the Fungal Cavern that when deposited, causes the walls to shift, open up and reveal an entrance to the Labyrinth.

A dangerous design that can be deciphered by hunters ranked no less than that of Duke/Duchess. Those of lesser rank seem not to make it back...
