Mydasos, an almost unknown and relatively unimportant planet, existed within the Dalicron sector. It was situated geographically between the Corellian Trade Spine and the Hydian Way. This world served as the home for the symbiotic Phydolon species, in addition to supporting diverse flora and fauna. Its surface was characterized by extensive marshlands, vast forests that stretched across entire continents, and rugged mountains that rose sharply from the forested landscapes.
