Underdark Encounters: The Rotted Expanse

For the past year I ran a D&D 5e game set in the Underdark, or at least my version of it that featured elements from Hot Spring Island sprinkled in. The players all played Underdark races and never once saw the sun (the one they saw when transported to Hot Spring Island doesn't really count) My players and I finished that campaign recently. There were magic eating constructs, evil deep gnomes monks, and medusa shock troops galore.

Along the way, I designed some fun encounter tables for the more dangerous regions the players traversed. Below is the table for one of my favorite regions: The Rotted Expanse.

Area Summary

Mushroom Men, meets Chernobyl, meets Salt in Wounds, meets that scene in Blade Runner: 2049 set in Dust Bowl Vegas. Three titanic beasts fought a battle, died and have been rotting ever since. In this section of the caverns is near impossible to breathe in unassisted as the air is choked with a yellow fog made up of spores and poison gases. The only things that thrive here are demons, rot, and Myconids. The myconids made the three slowly rotting beasts into their home cities and tend to be isolationist in nature. Occasionally, Underdark city states close to the Rotted Expanse send caravans through to trade with the myconids. These caravans are the safest way to travel as they provide breathing masks and strength in numbers. My players took part in one of these caravans.
