An era ends for Honkai: Star Rail on November 11, when the hit space-opera RPG rolls out its final Planarcadia update — headlined by a playable 5-star Aeon, per CBR.

That last detail is the one that matters most to players. Aeons have functioned as the gods of Star Rail's universe since launch: vast, story-defining entities that shaped the setting from a distance while remaining firmly out of players' hands. Putting one on the playable roster breaks a line the game has held for its entire run, and doing it as the capstone of the Planarcadia arc gives the era a suitably cosmic send-off.

End-of-arc updates in HoYoverse games tend to be the big ones — the moments when long-running storylines resolve and the roster gets its most consequential additions — and closing Planarcadia with a 5-star Aeon fits that pattern exactly.

For the broader player base, the update also marks a turning point: with this chapter wrapped, attention shifts to wherever the Astral Express is headed next. But first, the finale — and for the first time, the chance to pull a god.
