Structure and Rules

Participants and objective

  • Magi who receive the Grail's call are granted three Command Spells and may summon a Servant. Xi Jianxi receives his Command Spells only after agreeing to participate in the Fourth War 2.
  • Servants are temporary avatars of Heroic Spirits summoned from the Throne of Heroes; they normally answer the call because they possess desires for the Grail 3.
  • The conflict is structured around seven Servant classes, with the surviving Master–Servant pair expected to claim the Grail after defeating the opposition 3 29.
  • Combat before civilians is discouraged, but alliances, targets, and methods of engagement are otherwise left to the participants 7.
  • The Holy Church can issue emergency suppression orders against factions that threaten secrecy; defeating Caster is rewarded with an additional Command Spell 14 31.

Greater and Lesser Holy Grails

Component Function and condition
Greater Holy Grail The core system beneath Mount Enzou's Ryuudou Temple, where Servant souls are collected and converted into colorless magical energy under normal conditions 4 31.
Lesser Holy Grail A homunculus vessel that receives defeated Servants' souls; as more souls are collected, its physical functions progressively fail until it becomes the Grail's terminal 22 32.
Servant souls Their accumulation is required for the Grail's descent. The ritual's deeper Root-reaching function requires the death of the seventh Servant 29.
Command Spells Master privileges used to compel or reinforce Servants; they can also be replenished as a reward for extraordinary wartime contributions 2 31.

Locations

Site Relevance
Ryuudou Temple, Mount Enzou Location of the underground Greater Holy Grail cavern. Its specialized barrier repels Servants and spiritual bodies except through the main gate 4.
Tohsaka residence One of the spiritual-veil locations used for Grail summonings in previous wars; Assassin's opening attack occurs here 4 5.
Fuyuki Church A previous summoning site and the location where Xi Jianxi convenes the surviving factions to reveal the Grail's corruption 4 30.
Fuyuki Civic Hall Considered a theoretical Grail-summoning point, though no prior record confirms a summoning there 4.

Fourth Holy Grail War

Phase Chapter Events
Selection and summoning 2–3 Xi Jianxi receives Command Spells and summons Morgan, who identifies herself as Fairy Queen Morgan and accepts him as her Master 2 3.
Opening engagement 5 Assassin attacks the Tohsaka residence and is immediately repelled by Archer, exposing the disparity between participating Servants 5.
Initial alliances and clashes 6–14 Morgan battles Saber; Xi Jianxi separately confronts Lancer and Archer. Temporary cooperation forms among otherwise hostile factions in response to Caster's crimes 6 9 11 14.
Caster suppression 14–29 Caster's kidnappings and Sea Monster ritual trigger a Church-sanctioned subjugation. Caster is defeated, and his soul becomes the second collected by Irisviel 14 17 29.
Lancer's elimination 22 Xi Jianxi and Morgan defeat Kayneth and Lancer. Lancer's Spirit Core is shattered after Kayneth's death 22.
Corruption revealed 30–31 Morgan publicly presents evidence that the Greater Holy Grail is contaminated. Tokiomi, Waver, and Iskandar agree to halt the war and purify it 30 31.
Breakdown of the truce 36–42 Kirei and Gilgamesh continue operating outside the agreement, seize vessels for the Grail's activation, and forcibly activate the corrupted system at Ryuudou Temple 36 38 42.
Final battle and purification 43–46 The allied factions confront Gilgamesh and the activated Grail. After defeating the immediate threats, Morgan begins a purification ritual that strips the corruption from the Greater Holy Grail 43 44 46.

Corruption of the Greater Holy Grail

  • The Fuyuki system was jointly established by the Tohsaka, Matou, and Einzbern families under the witness of Grand Sorcerer Schweinorg 30.
  • During the Third Holy Grail War, the Einzberns summoned Angra Mainyu in the abnormal Avenger class. After its defeat, the being known as “All the World’s Evil” was absorbed into the Greater Holy Grail and contaminated it 31 32.
  • The corruption changes the Grail's mana from colorless to polluted and makes it a “broken tool” rather than a reliable wish-granting mechanism 30 31.
  • Wishes made through the corrupted Grail are fulfilled through extreme, destructive interpretations. Morgan warns that Artoria's wish to save Britain could require overturning established human history and provoke the World's corrective force 31.
  • Caster's manifestation as Gilles de Rais—an evil spirit shaped by later atrocities rather than a proper heroic reputation—is presented as evidence that the ritual has already malfunctioned 26.

Purification and Aftermath

  • Morgan determines that ordinary purification should be impossible, but succeeds because she rapidly deciphers the Fuyuki system and identifies how to remove the dormant corruption 46.
  • The ritual consumes part of the mana accumulated over sixty years to strip Angra Mainyu's influence from the Greater Holy Grail 46.
  • Once purification begins, the Grail lacks sufficient power to activate, ending the war and forcing the remaining Servants toward departure 46.
  • Morgan accepts Xi Jianxi's request to remain and form a new contract with him after the ritual's conclusion 46.
