According to myth, the Levitha River (largest river of the Seaborne Reach) was created by a gargantuan two-headed sea serpent that lives under the ocean. Purportedly, this serpent -- known as Levitha -- laid down in the Half Valley, creating indentations that formed the river. Accordingly, the river has tributaries that correspond to the arms of this gargantuan Naga-like creature, and it also has two mouths into the Sea of Himaat. Levitha also figures prominently in other myths indigenous to the region, and is prominent in naming of geological features (especially those of large size).
