The Maelstrom is a massive region of land and sea. It is named for the violent and turbulent seas that surround it. Both sky and water are hazardous to traverse, effectively cutting The Maelstrom off from the outer world. Lord of Maelstrom is set within this region, which comprises three continents: Andalar in the west, Vancar in the east, and Irfinden in the south. In the calm seas between Andalar and Vancar is the island-nation of Herculaneum. The seas separating the isolationist nation of Irfinden from Andalar and Vancar are more dangerous, and also house the Heart of the Maelstrom.
