Honkai: Star Rail has begun its next chapter. HoYoverse's space-fantasy RPG rolled out Version 4.3, 'The Lethe Below the Living,' on June 1, 2026, continuing the story of Planarcadia as the Trailblazer and Mortenax Blade venture separately into the mysterious World in Canvas.
The patch's headline arrival is Mortenax Blade, a 5-star Fire-Type character who walks the Path of Nihility. For long-time fans, Blade returning in a reworked, fiery form is a genuine event, and his character trailer, 'Nirvana,' frames the update's darker, more introspective tone.
Who to pull for
Mortenax Blade headlines the banner lineup, but he is far from the only reason to save your Stellar Jade. Version 4.3 brings reruns for Yao Guang, Cyrene and Phainon, giving players who missed them - or anyone hunting eidolons - another window to add them to the roster.
Into the World in Canvas
Story-wise, 4.3 pushes deeper into Planarcadia and the surreal World in Canvas, the arc HoYoverse has been steadily building since the Trailblazer arrived in this corner of the galaxy. Expect the usual generous mix of event rewards, login freebies and quality-of-life tweaks that accompany a Star Rail version update, all live now on iOS, Android, PC and PlayStation 5.
If you have drifted away from the train, a meaty new chapter plus a stacked banner schedule makes this a natural jumping-back-on point - just be ready for the Astral Express to take you somewhere considerably stranger than usual.
