The realm of Atlan was a waterworld, an endless ocean stretching into eternity. Here, the horizon stretched out into a seemingly infinite canvas of waves, tides, and whispers from the deep, where the rhythms of the sea governed the realm. The ocean pulsed with a vibrant, otherworldly beauty, a testament to the diverse civilizations that called it home. Beneath the surface, kingdoms of coral and crystal lay within the depths of the endless sea, home to the merfolk, sirens, nereids, aquari, selkies, and countless marine creatures. Towering kelp forests swayed in the deep currents, their emerald strands stretching toward the dim sunlight filtering from above. The depths were a tapestry of architectural wonders, each reflecting the unique culture and abilities of its inhabitants.
