Hors

Phaistos Porolan Tremanre Edolus
 * Phaistos is a small terrestrial with a trace atmosphere of carbon dioxide and xenon. The surface is scorching hot, and mainly composed of sulphur and various silicates. There is little of interest on this desolate world.
 * Porolan is an enormous terrestrial planet, half again the size of Earth. Despite its thick atmosphere, the weak output of the red dwarf Macedon leaves its surface biting cold. The crust is mainly composed of silica, but significant deposits of iron and other industrial metals are present.
 * Tremanre is a dwarf planet composed of light magnesium silicates, with deposits of aluminium. Its surface is covered by wide swathes of ancient, dark basaltic lava, possibly indicating the world was created through an impact with some other body in the system.
 * Edolus is a terrestrial planet with an atmosphere of carbon dioxide and nitrogen. Edolus' surface is covered by wide deserts of silicate sand, with only a few areas of igneous rock highlands to break the abrasive, dust-choked wind.

Solmarlon
 * Edolus' orbit is congested with debris thrown inwards by the gravity of the gas giant Solmarlon. Due to a high rate of meteor impacts, exploration is highly dangerous.
 * Solmarlon is one of Hors’ two outer worlds. Significantly removed from the rest of the system, and with unstable elliptical orbits, it is thought they may have formed within 3 AU of the star, and were hurled outward due to the instability of such an orbit.

Mawinor
 * Solmarlon is a hydrogen-helium gas giant with significant quantities of sodium in the upper atmosphere, giving it a distinct grey color.
 * Mawinor is the second of Hors’ outer worlds. It is essentially a rock of unremarkable ores with some deposits of water ice, but no minerals of value. The frozen surface is composed of silica.


 * Like the gas giant Solmarlon, it is thought that Mawinor formed too close to the Tereshkova stars and was thrown outwards by gravitational effects. Computer models suggest it will be ejected from the system in a few hundred thousand years.
