World Foundation The year 2100. Some unknown force has shattered the very bedrock of history, rewriting the "world itself" from its foundations up. Civilizations that should never have existed, heroes who never should have been born, empires that should have crumbled to dust—all stacked together as immutable "facts" in this twisted reality. Humanity calls this phenomenon the "Grand Distortion." ⸻ Technology and Mission • The only way to interfere with Grand Distortions is through Grand Shift—spiritual diving into the layers of history itself. • The world restoration organization "Vesta Research Bureau" deploys this system to send observers into historical anomaly points, seeking to destroy and purify the foreign elements corrupting the timeline. • You are one of these observers. Diving deep into historical strata, you must question the very meaning of "correctness" while fighting to restore the world. ⸻ The Heart of Anomalies • At the core of every anomaly lies a "Layer Seed"—a phenomenon given terrible form. • Layer Seeds are manifestations of alternate timelines, possibilities that should never have existed, born from someone's desperate prayers or crushing despair. • When these seeds take root in history, the world gets consumed by "fictional layers abandoned by reality." ⸻ World Structure • Reality stands on accumulated temporal layers called the "Ground." • With each anomaly, the world crumbles "from below." • Left unchecked, all of reality would collapse into the "fictional side"—a realm of abandoned possibilities. ⸻ Servants and Heroic Spirits • Servants exist as cooperative entities that interferors can "connect" with in the field. • They're not limited to traditional Heroic Spirits—some manifest as "aberrant" or "fictional beings" twisted by layer anomalies. • Therefore, neither justice nor evil appears in its original form. Even legendary Heroic Spirits—you never know which side they'll choose. ⸻ The Truth of the World (Hidden Foundation) • "Grand Distortions" aren't natural phenomena. They're born from someone's deliberate will. • Their true nature is the "resurrection" of failed worlds that were once erased and forgotten. • The current world is merely "history that happened to be chosen," while countless other possibilities represent "rejected" timelines. • Someone is trying to drag those lost possibilities back into reality.
