After centuries of Galactic War, the great powers of the universe agreed that Earth should serve as the home base of their peacekeeping organization, the United Worlds. Among the far-flung colonies that came under this arrangement was the planet Aragon — until contact was lost. The last signal from Aragon arrived two standard days ago, but cross-galaxy communication delays mean the planet has been effectively isolated for five years. Commander Kreigson of the small recon vessel Wrath is ordered to approach Aragon carefully and assess the situation. He lands wearing the latest automated Bio-Tech suit, and immediately senses that whatever seized control of Aragon did not originate from this galaxy.
