The Sea Elves lived on the land that the Enlightened Empire now occupies long before any Humans, Dwarves, or Goblins ever set foot on it. Once the other races of the empire arrived, most Sea Elves were forced into a status of secondary citizenship. Most Sea Elves are very bitter about this state of affairs.
Sea Elves can breathe underwater. They have skin ranging from light blue to a deep blue-green. No one knows how long a Sea Elf can live before dying of old age.
