Bloodbriar Hollow

Publisher's blurb:

Eerie swamp and marshes give way as you find yourself at the entrance into the depths of a cavernous rocky hollow. Passages fork off the main tunnel, one leading to a small chamber which then curves to connect to a small cavern full of tangle roots and rubble.

Another small cavern contains some ferns and bushes of watered down colors. A small pool of water can be found under a small overhang as you travel deeper into the cave system, It’s glass like surface perfectly still but it’s color tinted blood red.

The passage curves around and meets with a large cavern where above a bloody pool sits a shrine where a sword made of a crystalline nature rests.
