The War of the Waves was a conflict between the Sethai Federation and the Third Wave that took place between 209 AR and 218 AR, resulting in a victory for the Sethai.
Following the Great Cataclysm, the world of Eluneia was remade. Where once had stood great continents, now stood vast oceans, with survivors scattered across a variety of islands. What civilizations remained had slowly started rebuilding, with the Sethai Federation being the first nation able to rebuild its navy.
In the mean time, in the depths of the seas south of Tower Island, a new nation had formed, uniting a multitude of aquatic species not originally native to Eluneia under a single banner.
