====== Theory of Four Apocalypses ======
A prophecy circulates among the Omen Vanguards known as the "Theory of Four Apocalypses": that four Paths will push the cosmos toward the ending of "Finality." When Genius Society #83, Herta, had her third audience with Nous, the Aeon's extrapolations turned the theory from a seemingly baseless rumor into a fact that could not be ignored.

The first three possibilities are certain: the "Destruction," the "Nihility," and the "Harmony." The fourth Path, however, remains vacant... or has simply yet to manifest.

//Even Nous cannot calculate the next turning point of the universe's destiny. Though the future remains uncertain, the Astral Express must be ready.//
