The water-covered world of the Swell has been ravaged by the incursion of the moon shards as they make their way through the endless oceans, corrupting and transforming everything in their path. With little information and no clear direction, the remaining pockets of humanity press forward to retain what life they have on the dangerous waters. Vila Del'Sor has joined forces with what's left of the Deep Wardens to discover the secrets of the corruption and bring the refugees of the Planks to safety. Deep below the surface, Narrio Olitarth is not having a good time in the underwater prison of Grim-Mire Hold. And all is not well for newcomer Bal De Bao, a young Oceanid from Boola's Reach. Bal is on the search for something greater to do with their life. But when that opportunity comes, Bal is forced to reckon with their changing worldview and consequences for their actions–consequences they did not realize were ever on the table. The corruption spreads slowly, but the full moon's rise is approaching again. Mysterious forces are at play, machinations are in motion, and no one seems to know what's going on. Welcome back to the world of the Swell. Welcome to the Tainted Seas.
