A Greater Holy Grail War descends into chaos, half of its participants slain in one night. It’s up to the handful of survivors to pick up the pieces, determine who (or what) attacked them, then restore the crumbled arc of human history. The bereaved swordsman Aimon and the inexperienced magus Magdalena must summon forth their heroes and muster the will to fight before a foe of mythic proportions overwhelms our world once and for all.

Inspired by Fate/Apocrypha and Fate/Grand order, with an all-new retinue of Heroic Spirits from myth and history. Unlikely heroes and infamous legends alike will clash on the field of battle. Who will history side with?
