Fate/Grand Order THE STAGE - The Grand Temple of Time: Solomon Ars Nova

"A.D. 2017 The last era in which Magecraft still existed."

Tasked with preventing the destruction of humanity, the Chaldea Security Organization observes an anomaly: the Near-Future Observation Lens: Sheba proved the extinction of humanity in 2019. Chaldea pinpoints space-time Singularities thought to be the cause of humanity’s extinction and executes a forbidden ceremony called Rayshifting, where mages are converted into Spiritrons and sent into the past to restore humanity. Under the command of Romani Archaman and with the aid of numerous Servants, Ritsuka Fujimaru and Mash Kyrielight begin by restoring Singularity F: Flame Contaminated City, Fuyuki. From there, they make their way through seven Singularities, resolving each of them. And now, the path to the Final Singularity, Grand Temple of Time: Solomon, lies open, and the final battle against the King of Mages is underway.
