Lore & Background

The Prologue serves as the foundational narrative block for the entire Fate/Grand Order saga. It establishes the grim reality of the future where humanity has been extinguished, forcing the remaining survivors at Chaldea to take drastic measures. The organization utilizes forbidden time travel technology to correct distortions in history known as Singularities, hoping to restore a timeline where civilization survives. The title references the myth of Icarus, symbolizing both the danger of overreaching ambition and the necessity of flight to escape destruction. In this context, Chaldea represents humanity's final attempt to soar above its own demise. It introduces the core relationship between the Master and Servant, highlighting the bond required to wield magical energy effectively against supernatural threats. This arc also sets the tone for the series' blend of high-stakes sci-fi and mythological fantasy. By grounding the story in a near-future setting before expanding into ancient history, it creates a bridge between modern sensibilities and legendary heroism. The stakes are personal yet global, defining the mission that will span the rest of the game's timeline.

In Their Own Story

The sterile air of the underground facility hummed with latent energy. Ritsuka opened their eyes to the glow of monitors, memories fragmented like shattered glass. Da Vinci stood nearby, her expression unreadable behind a mask of professional calm. She spoke of a world that no longer existed, of humanity reduced to ash in a single year. In this moment, the weight of salvation settled onto shoulders too young for such burden. The summoning circle flared beneath them, light consuming the darkness as a new ally stepped forth from the void.

Reader's Guide

To prevent further destruction of history, Chaldea initiates the Human Order Reconstruction Project using time travel technology. The player must summon their first Servant to aid in this desperate mission against impossible odds. Mash Kyrielight is summoned as Shielder, an artificial Heroic Spirit designed specifically for protection and combat support. Together they face anomalies threatening the facility's stability while learning the mechanics of Command Spells and magical battle. This arc serves as a comprehensive tutorial for gameplay systems and narrative delivery before the true journey begins.
