A rambling maze of black tunnels blasted by fierce winds, Pandemonium is the most desolate and dismal of the known astral dominions. It is a place where the forgotten, the banished, and the lost wander without hope or rest, driven before the never-ending wind.
A dark and tempestuous portion of the Astral Sea surrounds Pandemonium. As the traveler approaches the dominion, roiling magenta purple clouds (the dominion’s color veil) press closer and closer, and the wind grows to a howling gale. A sudden burst of turbulence leaves the traveler sprawled on the floor of a vast cavern, and the seething clouds abruptly change into cold, black stone.
Pandemonium is a kingdom-sized labyrinth of long, winding tunnels and great caverns. These eventually return to their starting points, creating a sealed world-maze that no one has ever fully explored. The plane has no natural sources of light, and most of it is cold. The most dangerous feature is the violent, shrieking wind that buffets and torments any creature faring abroad.
