The Windswept Depths of Pandemonium

Pandemonium was made entirely of rock pierced by innumerable tunnels and caverns large and small. All open space was filled with howling winds that carried the sound of every word, shout, or scream uttered in the place. Without adequate protection, beings with hearing were rendered temporarily deaf in a matter of seconds and permanently deaf in a few minutes. Normal fires could not survive and there was no natural light. Conversation could only be accomplished by shouting at close range.
Gravity in Pandemonium always pulled away from the center of any cavern so a traveler could walk on the floor, walls, or ceiling. Streams and rivers would flow along one surface of a cave, or inexplicably down the middle through the air. The larger caverns were hundreds to thousands of miles/kilometers deep, wide, and tall, and the winds there could lift up small humanoids and carry them far away before a dangerous landing .Pandemonium has four known layers each with slightly differing conditions. Those four layers are Pandesmos, Cocytus, Phlegethon, and Agathion. There are no known indigenous life forms but plenty of inhabitants that were either immigrants, visitors, exiles, prisoners, or they were marooned here.
