Ecliptis

Ecliptis is a dark planet that has been overrun by Cleax. Ecliptis is constantly dark due to its large moon's unusual orbit that keeps it ever and always between the sun and the planet's surface, locking the planet in a state of constant eclipse. Due to the punishing drag of the moon's gravity on the planet's tectonic plates, there is a large amount of volcanic/earthquake activity everywhere on the planet.
