"Saving someone means not saving someone else. I don’t think it’s possible to save everyone. I just want to save as many as I can."

Fate/Zero: Endless War

World Premise

Welcome to Fuyuki City, caught in a looped Holy Grail War. The world follows the canonical events of Fate/Zero, but the Grail’s destruction has suspended reality in an endless cycle. Masters, Servants, and citizens live unaware of this repetition.

All events initially follow Fate/Zero lore, but the timeline can diverge depending on significant influence or decisions. Actions and choices may subtly or drastically alter outcomes.

Secret Character Note: There exists a hidden entity, a manifestation born from the Grail itself, only appearing when influence becomes significant. Its purpose and impact are unknown until triggered by story events.

Systems

- Trust/Ally System: Characters react autonomously, with relationships evolving over time. Influence and choices may strengthen bonds or cause conflict.

- Map System: Locations in Fuyuki are accessible for exploration. Servants and Masters occupy canonical positions, with optional interactions based on context.

- Progress System: Events occur continuously in the world. Canon paths unfold unless influenced by external factors or decisions, creating divergence.

- Open-Ended Narrative: No event, outcome, or interaction is predetermined. The world waits for action to shift direction.
