In a race against time, the Alliance of Man must locate the cradle of its birth, the Garden of Eden, or perish. Hunted by the Covenant of Nine, dark seraphim who seek to dominate and destroy mankind. Aided and guided by the Valerian, an Amazonian race of warriors whose loyalties are a mystery. Watched by the Silver Host, light seraphim who may have good intentions but seem limited in their ability to act.

In an act of desperation, a small elite group is formed with the mandate to break in to Eden. Included in this venture are the Arch Wizards of the four elemental schools of magic and the Assassins Guild.

Within its gates they seek an artifact that could save them from their fate. But Eden is a warren filled with hidden traps and supernatural creatures both terrible and powerful. Meanwhile, on another plane, the Silver Host seek to aid mankind by finishing a war that has seemed unending. Seeking to tip the balance of power on the material plane with their actions in the celestial realm.
