It is pitch black. You are likely to be eaten by a
grue.
~Zork
The grue is a sinister, lurking presence in the dark places of the earth. Its favorite diet is
adventurers, but its insatiable appetite is tempered by its fear of light. No grue has ever been seen
by the light of day, and few have survived its fearsome jaws to tell the tale.
What if you send the players in a dungeon that was already raided? Maybe you could have traps that are already set off, or the corpses of monsters etc.
