Leviathans have "King" or "Queen" in their name depending on gender.
Leviathans are the most powerful race in the Water Civilization. They resemble giant fish and other ancient creatures of the deep. With little gravity in the seas to affect their growth, Leviathans have become enormous and are sometimes mistaken for landmasses.
