Honkai: Star Rail - Rondo Across Countless KalpasBenghuai: Xingqiong Tiedao - Donghua Duanpian Yong Jie Lun Wu

In the merciless fight for survival, Izumo used the might of the Edict Edges to light up their uncivilized world of darkness in less than ten Amber Eras, building cities of dazzling neon lights.

That distant Takama Divine Realm, once so far away, became so close within their reach —

Yet history suddenly stopped there. The existence of the two planets instantly evaporated, disappearing into nothingness.

Nowadays, the past of the border planet Izumo can only be gleaned from the scattered whispers in the universe. Academics hold various views regarding its disappearance, but none can solve the mystery.

Izumo's history should have been a long flowing river, but it was severed in one cut, and all its past and future voided on emptiness' other shore.

Did it never exist, and was it no more than a fabricated story? Did its histories never occur, and it ran aground on the beach of reverse causation? Was it yet another appalling experiment by Dr. Primitive, or was it a sign of the Voracity returning from the end of the Cosmos?

Only that pitch-black great sun knows the answer, yet THEY remain silent, never speaking.

Because everything that had happened will one day regress to the end, and everything that had ended is guaranteed to happen again. The universe undergoes an eternal recurrence under THEIR shadow, and Izumo is nothing more than the footnote for an ellipsis.
