Fourteen hundred years after the millennial reign of the King, the world has strayed from the principles that led to humankind's greatest era: the Great Generation. The principal system of faith, Royalism, has become a politically oriented belief system. Responding to the growing threat to their beliefs, factions of the Royalist Social Movement seek to restore the principles and former glory of the Great Generation.|
High above Terra, connected by tethers stretching from the surface to sixty-four thousand kilometers in space, is the civilian space station City of Heaven-home to more than a million citizens. A futuristic Tower of Babel, City of Heaven is humankind's greatest achievement.
But, Ar'chaists, a radical sect of Royalism, are determined to force the world to bend its knee, with Ar'chaists assuming the Regency. In a single act of terror, they sever the tethers connecting City of Heaven, killing nearly all of its inhabitants and sending the city on a collision course with Terra, where millions more will surely die.
In space and on Terra, survivors battle for control and the polifaith movement reaches a crisis that threatens to unleash a new global faith-cleansing that will rid the world of Royalism once and for all.
