Castorice – Honkai: Star Rail

As Castorice grows closer to the Chrysos Heirs in Okhema, she is troubled by a recurring nightmare in which the black tide engulfs the holy city and her companions suffer terrible fates. The vision even ends with an interstellar visitor falling beneath the stars. At the Twilight Courtyard, a doctor encourages her to rest, but she resolves to do everything she can to prevent what she has seen. These feared events are presented as a nightmare, not as deaths already established in the waking world.

Amphoreus’s later story reveals that the history the characters experience is bound to a repeated artificial cycle. Castorice’s connection to Death is not simply an unexplained blessing bestowed on an ordinary child: earlier iterations of the story involve her twin sister Polyxia and an ordeal in which love, death, and the succession to the Death Titan’s authority cannot be separated. In an earlier cycle, Castorice sacrifices herself so Polyxia can take the authority of Death.

Polyxia, associated with Thanatos in the subsequent cycle, attempts to restore Castorice to life. The effort divides the authority of Death and leaves catastrophic consequences for the River of Souls. Castorice returns without an understanding of this past, while the power expressed through her lethal touch becomes part of the mystery she has spent so long trying to solve. These are events and disclosures belonging to the recurrence storyline, not separate adventures to be combined as if they occurred in one uninterrupted lifetime.

During the events of Through the Petals in the Land of Repose, Castorice journeys with the Trailblazer and Cipher toward ruined Styxia, where the vanished Death Titan, dragon bones, spectral residents, and the blocked River of Souls are connected. The search takes her into a nether realm where souls have long been prevented from passing on as they should. The expedition overturns her assumptions about the apparent source of her curse.

The central revelation concerns the severed authority of Thanatos rather than a simple curse cast by the dragon Pollux. Castorice encounters Polyxia and learns what her sister risked and lost. After the truth of their shared history emerges, Polyxia transfers the Coreflame of Death to Castorice. The woman who spent her life fearing her own hands becomes a demigod with a responsibility for Death itself.

Castorice does not treat acquiring the Coreflame as an uncomplicated victory or as permission to abandon the souls awaiting passage. She chooses to remain in the nether realm and help restore the cycle of life and death, sending the Trailblazer back to the mortal world. The farewell is deeply personal: she has found people she wants to be near, yet accepts a role that seems to require separation again.

After her departure, a fragment of Castorice’s recollection remains in Okhema. Through it, the Trailblazer can hear her gratitude for an embrace and her realization that her hands can convey warmth as well as loss. The encounter is explicitly a lingering reflection of memory while Castorice remains in the nether realm.

The wider Amphoreus conflict ultimately exposes the purpose of its immense recurrence and ends with the confrontation against Irontomb. In Version 3.7, the preservation of its people and their experiences in the work known as As I’ve Written changes what it means to say farewell to the Chrysos Heirs. Their remembered existence is sustained while a future rebirth into an independent world remains a process, not a completed instantaneous transformation.

In Beyond Time: An Eternal Page, Castorice reunites with Polyxia, Amunet, and others she once knew. Her curse has been dispelled in this preserved existence, and she says she no longer bears the authority of Death. She can finally accept physical affection and approach living creatures without endangering them. Learning to pet dromases, allowing others to braid her hair, and sharing ordinary time with her sister offer a tender contrast to the long isolation of Aidonia.
