Description
Originating from the Warring Ages of Belka, the artifact known as the Tome of the Night Sky (Buch der Nachthimmel) was initially a benign magical storage medium for archiving spells and knowledge. Later classified as a dangerous Lost Logia called the Book of Darkness (Buch der Dunkelheit), its transformation occurred when curious mages attempted to seal away the Tome of the Purple Sky and its master, Yuri Eberwein. This act corrupted the artifact's Defense Program, turning it into a parasitic entity that leeched energy from its masters.
The corrupted Book operates via interconnected systems: a core Master Program managing mana and Unison functionality, a corrupted Defense Program capable of infinite regeneration and data backup, and the Guardian Knight System (Das Schutzrittersystem). This system manifests the Wolkenritter, four humanoid programs tasked with collecting mana by draining Linker Cores or life forces. The Book contains 666 pages requiring completion for full activation. Masters could only communicate telepathically with the Book until 400 pages were filled, enabling full manifestation of the Master Program's personality. Physical manifestation and Unison Device functionality required all pages to be completed.
Historically, the Book cycled through masters, draining their life energy if pages remained unfilled. Upon completion, the corrupted Defense Program would kill the master, trigger a dimensional dislocation, and enter dormancy before regenerating elsewhere. In 0054, a Time-Space Administration Bureau (TSAB) task force secured the Book, but it went berserk. Admiral Clyde Harlaown halted its rampage through self-sacrifice.
In 0065, the Book bound itself to wheelchair-bound orphan Hayate Yagami. Unaware of its nature, Hayate treated the Wolkenritter as family, unintentionally fostering their emotional development. Seeking to save Hayate from the Book's life-draining effects, the Wolkenritter clandestinely collected Linker Cores, attracting the attention of Nanoha Takamachi, Fate Testarossa, and the TSAB. After the Wolkenritter were seemingly killed, Hayate triggered a Traumatic Superpower Awakening, allowing the Book's Defense Program to temporarily possess her. Hayate subsequently reprogrammed the Book, purging its corruption and renaming it "Reinforce." The Defense Program was destroyed by the TSAB's Arc-en-ciel weapon, while the Master Program sacrificed itself to prevent regeneration, leaving only an inactive fragment.
Following this, the purified Tome of the Night Sky became Hayate's primary magical instrument. She created a new storage medium modeled after the original Book and forged the Unison Device Reinforce Zwei. Hayate later joined the TSAB, utilizing the Tome's magic for interdimensional peacekeeping. The Wolkenritter, now independent of the Book, remained her loyal guardians.
Alternate continuities depict different fates. The *A's Portable* video games explore a timeline where Reinforce is not sealed, allowing the Book to regenerate its Defense Program, leading to conflicts involving dark clones of protagonists and time-traveling entities called Gears. The movies *Reflection* and *Detonation* introduce new threats stemming from remnants of the Defense Program, while Hayate's purified Tome remains operational. In *Force*, Hayate establishes Special Duty Section 6 to investigate the Eclipse Incident, applying expertise gained from managing the Book.
