在厄兆先鋒中，流傳著名為「四末說」的預言：四條命途會將銀河推向「終末」的結局。當天才俱樂部#83黑塔第三次覲見博識尊時，星神的演算令四末說從一則似是而非的流言，變成了不容忽視的事實。
前三種可能性確鑿無疑：「毀滅」、「虛無」、「同諧」。而第四條命途仍虛位以待，又或者尚未示現。
宇宙命運的下一個轉折點，連博識尊也無法用計算描繪其輪廓。前途雖不明朗，但星穹列車必須嚴陣以待。
Theory of Four Apocalypses (Theory)
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 extrapolation 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.
