Lore & Background

The First Singularity arises when the Holy Grail from the Third Fuyuki War is transported across time and space to London, acting as a catalyst for temporal decay. This event creates a paradox that threatens to overwrite the modern era with a distorted version of King Arthur’s legend. Chaldea identifies this anomaly as critical because its spread could destabilize the entire human timeline. The arc explores themes of legacy and redemption through Artoria Pendragon's presence in London, separate from her usual Japanese context. The corruption manifests as Phantasmal Creatures that feed on magical energy, turning the festive season into a battlefield where reality is fragile.

In Their Own Story

Snowflakes drifted silently down onto the cobblestones of Oxford Street, but the air tasted wrong—metallic and sharp with ozone. Ritsuka pulled their coat tighter, watching Mash check her device as the digital readout flickered crimson. Somewhere in the distance, a clock tower chimed midnight, yet no one was celebrating. The shadows between the gas lamps seemed to stretch longer than they should, reaching out like grasping fingers toward the two travelers who had fallen from the future.

Reader's Guide

Ritsuka Fujimaru and Mash Kyrielight depart Chaldea to investigate a temporal anomaly in London on Christmas Eve, 2004. Upon arrival, they discover the city is consumed by a Singularity fueled by a corrupted Holy Grail originating from Fuyuki. Their mission shifts rapidly from observation to intervention as the timeline begins to crumble around them under magical pressure. Teaming up with local Servants like Merlin and Medusa, the pair confronts distorted versions of history tied to King Arthur’s legacy. Artoria Pendragon serves as their primary ally against encroaching Phantasmal Creatures threatening to erase this era entirely. Battles take place amidst snow-covered streets where reality itself feels fragile. The climax involves neutralizing the Grail's influence without destroying the city or its people. Success stabilizes London but leaves Ritsuka with lingering questions about Chaldea’s true directives and Goredolf Musik's intentions. This arc establishes the core loop of time travel combat, introduces key mechanics, and sets the stage for future betrayals within the organization.
