The Deadlands

This area is a swamplike biome but the water is not liquid, it is instead a mix of decayed matter and bioacidic goo. Basically, you would be walking in a runny jello semiliquid made from the remains of unfortunate victims who did not have protection like clothes, leather, et c.

Strange bioluminescent fungi provide an otherworldly glow, but the swamps are fraught with danger from venomous creatures lurking beneath the surface. The air is filled with the sounds of croaking frogs and distant howls. Here, the magic is corrupted and twisted, leading to bizarre rotting mutations in flora and fauna. Travelers must tread carefully, for the swamp holds secrets of ancient rituals gone wrong. One can find ruins of ancient Bloodling strongholds, ritual sites, and more here.

Charred trees in a dense formation shows that long, long ago the Deadlands used to be a vibrant, lush grove.
