Khreianoa

The Khreianoa is the collective name for the three daughters of Khreus: The sea-goddesses Sherian, Nyra, and Shenoa. It simply means "the Daughters of Khreus" in classical Tuvai, coupling Khreus' name with the suffix "-anoa" meaning daughter or daughters (no distinction between singular and plural). 
The Khreianoa have a powerful impact on how the peoples of Urva view the oceans. The three have no love for one another and are often feuding, which mariners blame for all manner of storms, maelstroms, doldrums, rogue waves, and other such unpredictable dangers of the sea. Since Khreus herself was slain long ago and the domains of her daughters are as shifting and borderless as the ocean itself, the seas of Urva are often said to be masterless or unruled. And because Khreus and her offspring are all goddesses, the sea itself is also considered feminine by many peoples (the words for "sea" or "ocean" in elvish, Tuvai, and Chomarra are all grammatically female).
The maritime city-state of Thrommelport is home to a huge temple to the Khreianoa, which is one of the world's most important cult centers for the triple sea-goddesses.
