HSR 3.7 Story Ending Explained: Chrysos Heirs Fate

Honkai Star Rail (HSR) 3.7 story ending wraps up the Amphoreus arc with one of the most emotional finales the game has delivered so far. The Trailblazer wins the battle, but the story's final moments spark far bigger questions than “Did we defeat Irontomb?”

Players are left wondering what happened to Chrysos Heirs? Is Amphoreus really gone? Some even question why Cyrene's last decision feels heartbreaking and strangely hopeful.

You are not alone if you are still piecing together the meaning behind the HSR 3.7 story ending or trying to understand the real fate of the Chrysos Heirs. Keep reading as we clarify HSR 3.7 ending and explain how Amphoreus, the Chrysos Heirs, and Cyrene's sacrifice all connect to the larger Remembrance narrative.

HSR 3.7 Ending Explained: The Final Battle and Immediate Fallout

During the climax, the Trailblazer, Cyrene, and the Astral Express confront the Irontomb (the Emanator of Destruction). In the fight, the Irontomb strikes Amphoreus with a cataclysmic attack that appears to obliterate the planet. For a moment, it seemed the 33 million cycles of struggle led only to absolute annihilation.

As Irontomb took its final breath, it shattered into a corrosive virus that could threaten to infect the entire cosmos. To stop this, the Chrysos Heirs made the ultimate sacrifice and used their very spirits as arrows for Cyrene to fire and cleanse the threat.

The result is tragic, as the Chrysos Heirs and Amphoreus appear to be wiped out. Yet right after the dust settles, those same Heirs are seen aboard the Astral Express. That moment is revealed to be a memory reconstruction created by Cyrene.

What Happened to Chrysos' Heirs?

At first glance, HSR 3.7's story ending suggests the Chrysos Heirs died in their final act of defiance. They give up their spiritual essence to stop Irontomb's spreading corruption. It looked like a sacrifice that wipes out every last heir of Amphoreus, but it isn't the end of their story.

If we look closely at the HSR 3.7 story ending, it reveals that the Chrysos Heirs survive through Remembrance, preserved within the book "As I’ve Written". Before fading from the present timeline, Cyrene places the book into the Trailblazer's hands, which allows the memories of Amphoreus and its people to take form. The version of the Chrysos Heirs seen on the Astral Express immediately after the battle isn't a resurrection but a memory reconstruction created to ensure that who they were is never lost.

But memory in the world of Honkai Star Rail isn't static. Through the power of Remembrance, these memories can become real again. This is the central hope that defines the Chrysos Heirs' fate in HSR 3.7, and the game gives players multiple hints that Amphoreus and its people are already in the process of returning.

Amphoreus Isn't Gone — It's Being Reborn Through Memory

Players who complete the post-story quest "As I've Written" discover that Amphoreus is not just preserved as words on a page. Fueled by the Path of Remembrance, the memories within the book are forming the blueprint for a new and physical world. The Trailblazer's journey to share the book across different realms acts as a spark. It is a way to feed the Remembrance and strengthen Amphoreus' rebirth.

Herta and Screwllum also recover much of Amphoreus' original data from the shattered Emperor's Scepter, thereby accelerating its reconstruction. Herta directly confirms that Amphoreus will come back into existence, but it may take a year or ten thousand years. The timing is uncertain, but the outcome is inevitable.

Besides that, players who have a Chrysos Heir character on their roster receive in-game messages from them. These messages could not exist if the Heirs were truly erased. Instead, they are shown alive in a metaphysical-but-functional state, continuing to grow, joke, and live their lives as their world reforms.

This transforms the HSR 3.7 story ending from pure tragedy into a promise: "See you tomorrow" isn't a goodbye—it's a guarantee.

Cyrene's Final Choice and Her Unique Fate

Cyrene's decision is the emotional core of the HSR 3.7 story ending. She is given two options:

Cut ties with Amphoreus and live as an individual. Free to join the Astral Express and forge a new future.
Preserve Amphoreus as memory. Locking herself into the past and sacrificing her existence in the present.

Cyrene chooses the second path and gives up her future so Amphoreus can have one.

Her sacrifice stabilizes the timeline and seals off any chance of Irontomb's corruption resurfacing. It also traps her and the original Amphoreus in a causal loop, which means that she will not return to the main story anytime soon.

The best thing is that HSR does hint at something special. According to Elio's script, Cyrene may become one of the few beings who exist across past, present, and future, i.e., the same fate tied to candidates for the Aeon of Remembrance, which includes her and March 7th. Simply put, Cyrene may never return as herself, but she may return as something greater.

HSR 3.7 Story Summary

The HSR 3.7 story ending does not leave players in despair despite the destruction and sacrifice. It creates a rare balance that involves grief mixed with real hope.

Amphoreus is gone, but is already being rebuilt from memory into a new reality.
The Chrysos Heirs "died", but continue living as conscious beings through Remembrance.
Cyrene vanished from the present, but ensured her world's future.

Everything they fought for wasn't erased. It simply shifted from physical existence to memory, and from memory back toward reality.

The Amphoreus arc ends quietly, but its future is wide open. "See you tomorrow" no longer feels like a farewell. It feels like a promise the story fully intends to keep.
