Appearances
Parameters
Skills
- Territory Creation (B): Creates a workshop optimized for golem fabrication and Kabbalistic construction rites.
- Item Construction (B+): Specializes in artificial beings; mass-produces combat golems as disposable soldiers.
- Numerology (B): Kabbalistic number mysticism used to encode commands and strengthen constructs.
- High-Speed Incantation (B): Rapid deployment of golem magecraft in the field.
Noble Phantasms
- Golem Keter Malkuth · Anti-Army (A+): The perfected golem—an enormous artificial giant meant to become a new Primordial Human. Requires a core (often a living sacrifice in Apocrypha) and embodies Avicebron's dream of an ideal, sinless humanity.
Personality
Soft-spoken, melancholic, and detached from ordinary human warmth. Avicebron pursues the golem as philosophical salvation—an artificial Adam free of human cruelty. Polite yet willing to sacrifice individuals for the dream of a perfect being.
Story in Fate
Caster of Black in Fate/Apocrypha, Avicebron serves the Yggdmillennia faction by manufacturing golem armies. His true aim is completing Golem Keter Malkuth, a colossal artificial human. The tragedy of using his young Master Roche as a core defines his Apocrypha arc. In Fate/Grand Order he remains a golem specialist haunted by that ideal.
Relationships
- Roche Frain Yggdmillennia — Apocrypha Master; treated as both pupil and eventual core for Keter Malkuth.
- Sieg — Homunculus whose artificial nature resonates with Avicebron's themes.
- Other Black Faction Servants — Allies of convenience in the Great Holy Grail War.
- Kabbalists and golem legends — Conceptual peers in magecraft history.
Trivia
- Golem Keter Malkuth names sefirot (Crown and Kingdom) from Kabbalah.
- Design wears a mask/hood reflecting withdrawal from the world.
- Voiced by Mitsuru Miyamoto with quiet, weary intellect.
- Item Construction focuses almost exclusively on golems rather than general mystic codes.
