The Zaphar River begins in the Granite Hills, where it is fed by an underground spring. Travelling southwards through the continent of Sapience, it follows a primarily straight path, separating the Western Ithmia from the Northern and Eastern Ithmias, while a tributary of the Zaphar separates the Northern and Eastern Ithmias themselves. Further south within its waters lies the Isle of Delos, which temporarily bisects the river. It continues onward parallel to the Raphaelan Highway, through the Putoran Hills, before emptying into the Peshwar Delta. The spirit of the Zaphar, old man Zaphar, watches over the well-being of his waters from the Temple of Kastalia.
