Elu was born on the planet Rogue, one of the few in the Vegan star system with an eccentric orbit, during which Rogue passes close enough to the star to make the rock boil on the sun side, and yet far enough away thatthe atmosphere solidifies on the right side.

Roguians are possible the universes most obsessively shy creatures.Soon after birth they learn to produce a natural force shield that hides them even from each other. They are small, having high pitched voices, breathe oxygen, and must have eyes, ears and a mouth. 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.
