Ia, Goddess of the Seas

"Ia, Goddess of the Seas, the oldest of the remaining Ancient Ones." ~ Writing on the Statue of Ia in the Legendary Citadel of Zathos.

Orgins
Ia was born from the seas itself by Zathos. She was his first daughter. Ia was the only Ancient One until Zathos made Hestia and then Gallia.

War of Light and Dark
During the War of Light and Dark, Ia was one of the first to take up the battle against Malkir. Ia being one of the more powerful ones and perhaps the most powerful when she is in the water helped to stave off defeat time and again. Ia was insturmental in defending the Legendary Citadel of Zathos since it is on an island in the middle of the ocean. Against a vastly numerical force Ia, Hestia, Gallia, and Donar defended the Citadel with the help of the Immortal Guards, most noteably Vuriel. After the Battle for Legnedary Citadel, Ia sank all of Malkir's forces that were retreating. With this loss Malkir's army was greatly reduced in strength. Malkir would be defeated within the century.

Post-War of Light and Dark
Following the Light and Dark War, Ia returned to Poseidon, a fortress in the sea. Poseidon is virtually unreachable by any that Ia doesn't want to be there, and the safest place for those that she allows there. Over the next several millenia Ia will watch over the mortal races aiding those that follow the Church of Zathos. She goes on to create horses giving them to the mortals.
