Home to four species — Humans, Newman, CAST and Deuman — the great fleet known as "Oracle" has crossed countless galaxies and discovered worlds beyond number. To advance its mission, groups called ARKS were formed to explore and research each newly found planet.
But deep in space, a deadly threat emerged: the Falspawn. Spreading like a virus, they infected the inhabitants of various worlds. Once their weakness — Photons — was discovered, ARKS took on a new purpose: to defend the universe from the Falspawn.
