A unique aquatic species of Riven. They resemble seals with long necks and snouts. They are communal and intelligent not unlike dolphins.

With their lumbering bodies and strangely delicate flipper appendages, these mammals seem like refugees from some bygone era. Despite their physical size, they are passive in their quest for food: using an efficient baleen (bony plates instead of teeth) feeding mechanism, they ingest the colonies of microscopic organisms that thrive in these waters. They have distinctive dual-colored hides.
