Pandaemonium is the castle of Emperor Mateus when he becomes the king of hell in FF2. The main area is a closed in space with many walls and in the center is a large pit with three square platforms hovering in midair.

The other part of this arena is the roof of the castle which is a sprawling floor with many crystals that can be used as platforms sprouting up in many places along the floor. In the distance is Mateus' throne.
