Schemes of the Lich King
The former Wizard King’s palace was built on the largest island of the sea that was then known as Stormmaker. After the Dragon Emperor slew the Wizard King and destroyed his palaces (building the new capital of Axis on the sea’s western shore), the island lay fallow for decades. As the power of the returned Lich King asserted itself, however, the island that had been his capital sprouted great mausoleums and rings of cemetery catacombs. The wizards of Horizon say that the Lich King’s magic brought the formerly loyal subjects of his kingdom back to unlife and consolidated their grave sites and memorials on his former island fortress.
Like the other ancient graveyards scattered across the world, the tombs of the island require maintenance and sacrifices to keep them from sending forth impossible hordes of undead. By trial and error, the Gravekeepers of the Empire have learned that the great island now known as Necropolis can be kept safely dormant so long as a steady procession of sacrifices is made around the island’s outer ring. Venturing into the center of the island is too dangerous for all but servants of the Lich King and powerful adventurers.
If the sacrifices falter for any reason, history has taught the Empire that the undead swarm through the ocean and emerge onto land all around the Midland Sea.
