From the back cover:
Millennia ago, long before the Dark Legion came to our hapless solar system, the four great merchant corporations ruled supreme over the human worlds.
Mishima took Mercury, Capitol took Mars, and faithful Bauhaus took fair Venus, the emerald jewel, as its own. The Homebuilders carved out a place for themselves in the fertile lands. They conquered the frigid icecaps and the stormy seas. They made themselves a home in the stars.
But then the Great Darkness came, and Venus' raging surface was scarred by citadels and by unending war. Algeroth himself strode the planet, and Humanity was helpless before him.
From the Homebuilders' ranks stepped Nathaniel Durand, the First Cardinal. It was he that brought the Light back to us, that led the fight to beat back the Darkness. But the battle for Venus and for the rest of Humanity is far from over.
Now is the time for heroes.
