When the 3.8 Honkai: Star Rail patch debuts on December 17, 2025, it also means the story will head back to Penacony for a bit now that the Amphoreus storyline is done. This will involve a new Trailblaze Mission with Constance, known as The Dahlia, involved. It will also be the stop before the next planet in the Astral Express’ journey. HoYoVerse also confirmed the 3.8 patch will be in effect between December 17, 2025 and February 13, 2026.
The 3.8 Honkai: Star Rail trailer revealed that the Astral Express will be back at Penacony because of The Dahlia. She has the ability to affect people’s memories, and she claims there are details that we missed from the Penacony adventure. As a result, before we head out on an entirely new leg of our journey, we’ll see Firefly’s perspective from the events of the Charmony Festival.
Because of the extended run of this patch, the schedule for 3.8 Honkai: Star Rail banners and events will be different. The first phase will run between December 17, 2025 and January 7, 2026, and that features The Dahlia and Firefly as the five-star featured units. Gallagher, Luka, and March 7th will be the focus four-stars. The second phase will be in effect between January 7-28, 2026, with Fugue and Lingsha as the five-stars and Arlan, Natasha, and Sampo as the four-stars. Finally, a third phase of character banners will appear between January 28, 2026 and February 12, 2026. That will feature Aglaea and Sunday as the five-stars and Dan Heng, Tingyun, and Yukong as the four-stars.
Here is the full trailer for 3.8, which will be known as “Memories are the Prelude to Dreams.”
