Bloody Sacrificial Shrine

Publisher's blurb:

A river flows below the cliffs from an underground passage and past the site of a sacrificial altar, which is watched over by three stone guardians. The jungle is almost as thick here as it is hot.

Ferns and trees are covered with vines and large roots jut from the earth. An old stone path can be seen below the undergrowth making it’s way up to the altar where a dagger sits. Used recently in a sacrifice to the gods, the river below running red with the blood of those killed.
