The Corvathian tribes used to rule the sea with their feared Corvairs, swift ships specially built to be sailed with the assistance of a skilled crew led by a Wavecaster, a specialist spellcaster who controlled wind and water to the ship's advantage.
Hunted to extinction by the navies of the Northern Empire the last of the Corvairs were sunk a generation ago. Now in the wake of the War of Three Magicks, a few rich families of the Northern Empire try to keep a grip on the seas, restricting the proud Corvathian seafares to single masted fishing boats. However, sensing opportunity the Corvathians have become bolder, building bigger ships and harvesting more of the riches of the sea. Some have even begun pirating the smaller Northern ships, dreaming of restoring Corvathian dominance in the Northern Sea.
