Epho

Description
Epho is a rocky world with an atmosphere of oxygen and carbon dioxide. There are large craters scattered across its surface, obviously from hypervelocity kinetic impactors. Stretching between these locations are the shattered remains of magnetic levitation rail lines, which strongly suggests that the craters represent the former locations of arthenni mining outposts or other settlements. The equatorial region contains an extensive network of canyons formed by the planet's abundant liquid water. TRAVEL ADVISORY: Epho's atmosphere is approximately 41 percent carbon dioxide at sea level. This is four to six times the level necessary to render most species unconscious within a few minutes of breathing it. Breathing masks must be worn at all times when on the surface of Epho.
