Every so often in a published module you get a room that seems to have been forgotten about by the module designers. In Thunderspire Labyrinth we get this small room up the back of the Horned Hold, sandwiched between the Ruined Chapel of the wights and the Duergar Slave Pits.
The module calls it the "Crypts", and offers the following descriptive text: "The remains of about two dozen minotaur warriors lie here in burial niches along the walls. In the southern hallway stands a statue of a grim-looking skeletal minotaur with a greataxe - a minotaur version of the Grim Reaper."
That sounds like the setup for an awesome undead-themed encounter. Even as your players make their way into this room, they'll be sharpening their weapons and patting each other on the back and declaring, "Oh boy! The Minotaur Grim Reaper!" The skeletal reaper is a classic archetype, and here we have a new bull-headed twist on the idea. It's a great way to build on the undead from the last encounter and really tie the Horned Hold into the ongoing minotaur-themed history.
Unfortunately, yet again, it's not to be. The statue doesn't come to life; the dead don't rise from their graves. There is, in fact, no tactical encounter for this room whatsoever, making it the only part of the Hold not covered in this way. Players will be completely baffled as to why nothing in this room is animating and trying to kill them. It does, after all, run contrary to their entire previous experience.
We can't be clear on exactly what was going on here. An oversight by the developers? An encounter cut to fit the page count? Or just a minotaur crypt that genuinely doesn't present a danger to adventurers? We may, in the end, never know.
