This mod is a half-joke mod—meaning, while the concept started as a joke (it is the Pneumonia Dweller, after all), I actually tried to make it a solid experience. The mod itself is pretty simple: it adds a new biome and a few structures to explore.
I hope you have fun!
(p.s: geckolib is required)

Also: Hellish Horrors v1.3 is almost finished—sorry for the wait!
NOTE: This mod is not intended to be actually scary, by the way!
