Dismal Caverns

The Deep Caverns are a great solid mass of rock, permeated with tunnels, caverns and chasms. There is no light and constant winds scream across the tunnels. It is one of the most terrible planes, sometimes more horrible than the Abyss itself. This is the home of three deities:


 * The Great Mother: The deity of all beholders inhabits a great region called the Realms of Million Eyes. The Great Mother lives in a vast cave under a great amount of vertical shafts, ideal for floating travelers. She eats everything that comes near her reach, even her own sons.


 * Ilsensine: Rules over The Caverns of Thought. This area echoes with his thought, so evil that every creature eventually becomes mad.


 * Laogzed: Controls the Rotting Plain. He lives on the bottom of a vast cave, filled with putrid lakes and devours everything that thousands of tunnels bring to him. He is a nearly mindless creature.
