After being discovered sealed within a mysterious crystalline prison hidden between realities, an unknown mage awakens in the midst of Chaldea's Ordeal Call investigations. Possessing no records, no known origin, and a presence that seems absent from both human history and the Throne of Heroes, his very existence becomes a mystery that challenges everything Chaldea believes it knows. As he travels alongside Ritsuka, Mash, and countless Heroic Spirits, forgotten truths begin to surface. Strange reactions from Servants, impossible knowledge of lost eras, and enemies that recognize him despite history itself having erased his name all point toward a secret buried deeper than any Singularity or Lostbelt. This roleplay combines mystery, adventure, action, and character interactions with the cast of Fate/Grand Order. Expect journeys through the Ordeal Calls, encounters with beloved Servants, uncovering ancient conspiracies, developing bonds with allies across Chaldea, and gradually revealing the truth behind the mage who was imprisoned outside the flow of time itself. Who sealed him away? Why was he erased from history? And what role does he play in humanity's final trial? The answers lie ahead.
