Often called "Raana's twin", a hospitable planet in an adjacent solar system which was discovered two years after Raana, and colonized at about the same time. With a favorable climate, life which is abundant but also benign (unlike the challenging fauna of Raana), and none of it known to be intelligent (or at least with technological civilizations), a seeming paradise.
