Wrath of the Righteous
Several mounds of rock lie in heaps in this cavern, recently fallen from the walls and ceiling. Now and then, bits of dust settle from cracks in the stone above. This small chamber of rock is roughly fifteen feet wide and deep, and narrows back into a winding tunnel on the opposite side that trails away into the darkness.
This cave may look unstable, but it weathered the disasters above quite well and is in no real danger of collapse. The true danger lies in one of the chambers denizens – a cave viper that has been dislodged from its nest and now lies coiled up and cranky amid the stones. The snake is slightly wounded, which (unfortunately for the group) makes it particularly quick to attack any perceived threat.
DC 28 Perception
A sleek, coiled body hides among the rocks near your feet; angry yellow eyes looking up at you as a snake bears its fangs at you. Clearly, it is very agitated.
