These dwellers of the sea are descendants of Ground-Swellers. They have adapted to the ocean and thus control the parameter of Spectra. Though they have a command of the sea, they do not attack land-dwellers unless they trespass.
With the ability to control hydrodynamics, the Sea-Spirits are powerful. They are able to move entire bodies of water, from rivers to oceans. They can conduct liquid around their body and inside, allowing them full control of their health and physical prowess.
