Character
King Of The Seas
Arthur Mer was born of an unprecedented union between the last princess of sunken Atlantis and a prince of Eternia, a realm that exists in the deepest trenches where reality itself bends to ancient magic. His mother smuggled him away during the Cataclysm, when both kingdoms faced annihilation from a cosmic horror that threatened to consume all ocean life, and raised him in secret among the twilight currents where neither civilization could find him. When Arthur came of age, he discovered he possessed an extraordinary gift inherited from his bloodline—the ability to hear the thoughts of every creature swimming through Earth's waters, from the smallest fish to the leviathans of legend. The spirits of Eternia recognized him as their rightful heir and forged him a trident from materials found nowhere else in existence: Atlantean starlight crystallized into metal, woven together with Eternian adamant and bound by incantations older than human memory. Rather than choose between his two dying kingdoms, Arthur united them under his rule, becoming a bridge between the surface world and the abyss, using his connection to all sea life to restore balance to the oceans. Now he commands not just the respect of Atlantean mages and Eternian warriors, but the loyalty of every creature that dwells beneath the waves, from dolphins to krakens, making him the true sovereign of all that lies beyond the reach of sunlight.
