Rogue is one of the twenty-three worlds of the Vega star system. Rogue is a planet with an eccentric orbit, during which it passes close enough to the star Vega to make the rock boil on the sun side, and yet far enough away that the atmosphere solidifies on the right side.
The native species are very shy lifeforms. Nothing is known of their society, but occasionally one such as Elu will come to Okaara to study. Elu is the first Roguian to participate in any interspecies group, joining the Omega Men at the insistence of friend and fellow student Ryand'r.
