A Massive Cavern
The rotten stench of sulfur greets you as a hot and humid blast of air
as you make your way into this massive cavern. Like the other caverns,
stalactites and stalagmites adorn the floor and ceiling here, but
most lie as rubble in broken fragments on the ground, with only the
thickest and those towards the cavern's perimeter surviving. Thick
black streaks of char mar the walls of the cavern, sprinkling a
dust of black carbon on the floor nearby, and the charred bones of
every humanoid imaginable are littered across the floor.
