在厄兆先锋中，流传着名为「四末说」的预言：四条命途会将银河推向「终末」的结局。当天才俱乐部#83黑塔第三次觐见博识尊时，星神的演算令四末说从一则似是而非的流言，变成了不容忽视的事实。
前三种可能性确凿无疑：「毁灭」、「虚无」、「同谐」。而第四条命途仍虚位以待，又或者尚未示现。
宇宙命运的下一个转折点，连博识尊也无法用计算描绘其轮廓。前途虽不明朗，但星穹列车必须严阵以待。
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.
