After years of tension, war has finally come to the Union worlds. Hordes of rebels, seeking revenge for their lost worlds, ravage the Peripheral Zones. One of the leaders of the rebellion is Charon Antares. When another one of his braver mission ends in disaster, the rich and powerful sovereign plans to deprive him of his authority. To save his status, Antares agrees to execute her insane order that may cost the lives of thousands of his people. A young and easy-going girl named Cerridwen lives in a peaceful world. When she finds out about the tragedy that happened to her family, she vows revenge, but without collaboration with Antares and the rebels, she will not be able to fulfil her plan. Meanwhile, a group of the Union scientists decides to end the rebel’s invasions, once and for all - they build a deadly, inhumane weapon out of sight of the government.
