This planet is not native to the system. It traveled from elsewhere in space until it was captured by the sun's gravity. It orbits at 45º from the system plane.
Rogue has an extremely thin atmosphere. The surface of Rogue is dotted with large craters. What atmosphere does exist is extremely radioactive. A series of silicate lattices are noticeable from orbit near the polar regions. These lattices are in fact home to a silicon lifeform the Aeon crew named Kamakiri because of their appearance.
The crew of the Aeon named the planet Rogue due to its origin.
