New Earth.

Three hundred years of war between the planets Earth and Mars caused much devastation, finally the UNOE Congress and the Martian king made an uneasy truce.  But then a UE spay detonated a bomb in the martian palace, killing the king and hundreds of others.  Mars fired it's fusion bombs on Earth, killing thousands.  As the new war raged on, a group of desperate Telluric and Martian humans gathered on Mars and built a vast ship, dubbed it the Ark, boarded it and flew off, to the binary Alpha Centuri system.  It took years to get to Alpha Centuri, all the passengers were put into cryostasis.  When they reached the Centuri system they found five giant gas giant; Rhea, Cronus, Oceanus, Hyperion, and Prometheus. Hyperion was surrounded by four moons; Eos, Amphitrite, Apollo, and Persephone.  The two suns were dubbed Helios and Hephastus.  The refugees landed on Persephone, a lush, spring-time moon.  But it was already inhabited by a humanoid alien species: the xali.  Eos was inhabited by none, Amphitrite was inhabited by the ieu, and Apollo was inhabited by the ner'i.  War was coming to the Alpha Centuri system.
