The books begin in the Year of the Fall 1103, when the protagonist Raj Whitehall and his friend Thom Poplanich stumble on a still-working remnant of the old technology, the quantum supercomputer "Center", which Raj and Thom regard as an angel. Center describes itself as a "sentient artificial entity of photonic subsystems tasked with the politico-military supervision" of Bellevue. Center charges Whitehall with uniting Bellevue and provides him, through a constant mental link, with predictive visions that simulate probable situational outcomes, historical data, eidetic memory, and minor enhancements to physical abilities including accuracy with firearms. Raj couples these assets with his own charisma and skill to become an extremely effective military leader. Meanwhile, his wife Suzette quietly uses her own highly developed court intrigue skills to neutralize Raj's political foes and obstacles behind the scenes, compensating for his more direct tactics.
