Elymia

Elymia is one of the Sustainer Gods, Gods that guard a certain object or collection of objects in the mortal world. Elymia is the Goddess of Water.

Creation and The Great War
When the greedy Cerosceian King, Gallart the Arrogant, waged war against the Gods themselves, the Nature God, Nikolaide summoned Elymia and the other Sustainer Gods to destroy their opponents. The Sustainers swore an oath, to purge all evil towards the Gods through merciless slaughter. They sent plagues, monsters and disasters to the Cerosceians, which greatly damaged their once stunning civilization. Elymia summoned a massive sea serpent, known as Gladrys, which attacked and killed the queen and prince, and almost killed the young princess, Durandal. Durandal was the only survivor of the Great Cerosceian War and sought to take revenge.

Life As A Human
Many thousands of years after the fall of Cerosceia, humanity managed to reestablish its civilization and all the Gods took on humanoid forms to live alongside their creations. When the nation of Nebre-Tsushira, independent from the United Kingdom of Earth was created, Elymia took on a humanoid form and decided to stay there. She became a mentor of water magic and named herself Eruma to hide her identity. She taught Sedna to use water magic and gave her her iconic Trident Lance. After she had completed her goal of spreading her teachings to humans, she returned to her draconic True Form and returned to Yggdrasil, the Realm of the Gods.
