Danom

Danom is a land of immense magic and riches, just a little farther West than the continent of Siemas. At its center is the Heart of the World, an object of profound worth, though its exact form varies depending on who you ask.

Mostly, Danom is thought to exist only in the tales that sea sailors weave, sort of like El Dorado or Atlantis. However, Danom is actually a living underwater city, populated by dolphins, whales, humanoid fish-people called Sahuaguin, and Dragon Turtles.
