As an entry in The RPG Geek Spring 2017 Revisionist Challenge, this is an expansion of The Parched Throat entry in the One Page Dungeon Contest 2013.
This is the barest core of an adventure. It’s really just a deep pit with stuff in it. Use it as a filler or one-shot for a well-funded and well-prepared party, or use it as the core to longer, multi-session adventure. However, don’t expect a fully-scripted adventure that can be run without preparation.
