Lemegeton

Lemegeton is the damaged remnant of the myth-ranked grimoire created by King Solomon to govern his contracts with seventy-two great demons. The surviving fragment calls its ego Ars Goetia and, after making a temporary contract with Theodore Miller, usually takes the form of a silver ring on his right hand.

History

Discovery in the Zero Library

Theodore finds the jeweled prohibited book in Meltor's sealed collection. The fragment reacts fearfully to Gluttony, which recognizes it as less than five percent of the original Lemegeton's performance. Appraisal describes a grimoire damaged by more than ninety percent: most of Solomon's system has been lost, leaving the imprints of only three senior great demons—Nebiros, Foras, and Flauros—rather than the original seventy-two. (Chapters 313–314)

Rather than consume a damaged source and lose its autonomous functions, Theodore offers it a temporary contract. A permanent demonic-grimoire contract would conflict with his existing divinities and Gluttony, so Goetia accepts the limited arrangement and discloses its name. The thick book turns into a silver ring, avoiding Theodore's left hand because Gluttony resides there. Its sub-ego and secondary processing immediately increase his effective casting speed and help manage magic operations. (Chapter 314)

Goetia's later service

Goetia develops from a frightened remnant into a loyal and opinionated assistant. It can maintain support spells through isolated circuits and later becomes the control key for the facilities of Meltor's central magic tower, including its space gates. Theodore assigns sub-master authority to others while retaining the highest command priority through the ring. Even with roughly eighty percent of Lemegeton's function still missing, Solomon's design provides security that contemporary intruders cannot easily break. (Chapters 322, 342, and 380)

The ego also retains Solomon's memories and tastes in limited form, including its creator's reliance on it when choosing gifts. Solomon later recognizes Lemegeton as his connection to Theodore while helping reconstruct Theodore's soul in the Akashic Records, although he refuses to call Theodore his successor. The grimoire's continued service therefore establishes a relationship, not a transfer of Solomon's title or full power. (Chapters 381 and 394)

Abilities and limitations

• Sub-ego processing: Goetia can conduct secondary calculations, manage spell upkeep, isolate circuits, communicate through linked facilities, and respond as an autonomous assistant. Theodore remains able to issue overriding commands. (Chapters 314, 342, and 380–381)
• Demon imprints: The damaged fragment preserves Nebiros's Pain, Foras's Transparency, and Flauros's Burning Eyes. It has lost the overwhelming majority of the original contracts and cannot reproduce complete Lemegeton. (Chapter 314)
• Transformation: After contracting, the prohibited book becomes a compact silver ring. The form acts as Theodore's key to systems built around Goetia's authority rather than as proof that every one of Solomon's ten rings survives. (Chapters 314 and 380)
• Central-tower control: Lemegeton governs the central tower's facilities and security hierarchy, with Theodore as master and designated users holding reduced authority. This function depends on the tower Theodore designed around it. (Chapter 380)
• Contract limits: Theodore deliberately chooses a temporary contract to avoid conflict among demonic power, his divinities, and Gluttony. Goetia supports him without replacing Gluttony's predation or granting Solomon's full magical standing. (Chapter 314)
