The Gyre Arkwyrm, known as World Swimmers or Sea Monarchs, is a large, migratory species that evolved in the sunlit zones of the ocean. They measure 120 to 150 feet in length and are characterized by their broad, flat backs which support diverse marine ecosystems. Not threatened, they depend on expansive deep water for survival. Their diet consists mainly of plankton, which they filter through baleen-like structures. The Arkwyrm possesses unique abilities such as creating cyclonic water spouts and manipulating ocean currents. Highly intelligent and peaceful, they travel in small family groups, communicating through melodic sonar songs. Their lore includes being seen as saviors by stranded sailors, and they are known to accumulate unusual objects in their throats over time. The species plays a vital role in the ecosystem, enriching the ocean with their presence and waste.
