The Golden Wastes
The Great Beasts are the servants of the Ancients and work to free them. The Great Beasts, like their masters, lie trapped under the earth, but unlike them are awake and stirring. Should any one of them escape, it would be a great catastrophe that would ravage the world. The Great Beasts have spawned lesser monstrosities to help them. The Great Beasts are often considered to be the gods of the various intelligent monster races who war with man over dominion of the world.
There are many Great Beasts, the most famous of which is the Great Maelstrom which sleeps under the seas and sends his dreams to his servants, the Drowned Brotherhood. Almost as famous are the Conqueror Worm and the Black Goddess. After them are lesser known Beasts, but all equally destructive and terrifying like the Devouring Flame or the Walker of Winds.
The Great Beasts are not invincible however, and legend records it is possible to destroy them should they awake and make their way to the surface. In the Epic of Darkness, a collection of legends and myths about the Ancient Sea Kings and their accomplishments, it is recorded the Sea Kings defeated the Scuttering Madness; a revolting, slavering, obsidian abomination with the carapace of a beetle. Its dozen barbed tongues dropped acid and snatched men into its gaping maw. The horn protuding from its head would devour arcane energy and radiate back a necrotic, phantasmal madness. The Epic describes it as “a sky-filling darkness that flies on four hellish wings, vomiting always death.” It laid waste to several colonies of the Ancient Sea Kings before an assemblage of their greatest heroes destroyed the Beast. Alas, the Epic does not accurately describe how the black titan was felled.
