Dan Heng

The Stellaron Hunters know much more about the protagonist than he does. Before losing his memory, the Pathfinder traveled with Kafka for a long time and was part of their crew. The Hunters genuinely care for the protagonist and protect him from the outside, as Elio's script calls for the Pathfinder to play a key role in saving the galaxy.

Elio ("Slave of Fate"): The leader of the organization, who rarely appears in person. He has the ability to foresee the future. In the game, he is often associated with the black cat that appears in Hunter artwork.
Kafka: Elio's right-hand woman and the "mother" of the Pathfinder (she is the one who awakened him in the prologue). An elegant and cool woman who wields katanas, submachine guns, and hypnosis ("Whispers of the Spirit"). Due to a rare illness, she is physically incapable of feeling fear.
Silver Wolf: A genius hacker from the punk planet Panklord. She perceives reality as a giant video game and is capable of "editing" the data of the universe itself (changing enemy weaknesses, hacking reality).
Blade: A grim swordsman and former friend of Dan Heng of the Cloud Quintet. He has acquired cursed immortality and suffers from mental insanity ("Mara"). Blade longs to die, and joined the Hunters because Elio promised to grant him a wish at the end of his journey.
Sam (Firefly): A genetically modified pilot from the fallen Glamoth Empire who fights in the massive, mechanical "Sam" armor. Firefly suffers from entropy loss syndrome (her body is slowly disappearing), and the Hunters are her chance to find a cure and live as a normal human.

The Stellaron Hunters are a mysterious and dangerous organization in Honkai: Star Rail that travels the universe to harvest Stellarons. In the eyes of the Interstellar World Corporation (IMC), they are considered the most wanted criminals in the galaxy, with astronomical bounties on their heads [ru-wiki]. However, their true motives are far more complex than they appear.
The Hunters don't wreak havoc for pleasure. They unquestioningly follow the prophecies of their leader, Elio ("Doomslave"). Elio sees the future and calculates the only scenario in which the universe can survive the coming final battle against the Aeon of Destruction—Nanook.
Every "crime" or appearance of the Hunters actually pushes Star Express toward solving the Stellaron problem. Essentially, the Hunters act as behind-the-scenes directors, transforming the Pathfinder into a hero capable of saving the world.

Credits are the main and most common currency

The mysterious, furry, and extremely responsible conductor of the Star Express. Pom-Pom fanatically maintains the cleanliness of the common car, checks the technical condition of the train before jumps, and stocks up on supplies. The boss on board: Despite the cute appearance of the long-eared creature in the oversized cap, Pom-Pom is an unquestionable authority. Even Welt and Himeko obey the conductor unquestioningly when it comes to the rules of conduct on the train. Relationship with the player: It is Pom-Pom who gives the Pathfinder rewards for increasing their Mastery Level and often asks for help with small errands (for example, removing Himeko's coffee stains or fixing a jammed door).
Pom-Pom is physically unable to leave the train and disembark on the planet's surface. The exact reason is unknown, but the conductor is literally bound to the magic of Exploration. Hypersensitivity: Pom-Pom feels the weight of every passenger on board and instantly notices the presence of "stowaways" or foreign objects in the carriages. Sentimentality: Pom-Pom's greatest fear is loneliness. When the Nameless leave for long periods to explore new worlds, the conductor becomes deeply sad and cries tears of joy when everyone returns safe and sound.

A calm, sensible, middle-aged man with glasses. Due to his vast life experience, he acts as a mentor to the Express youth. Hobbies: In his free time, Welt enjoys drawing storyboards, as he was a successful animator and cartoon director in his home world.
Joachim Nokianvirtanen. He inherited the title "Welt" and the surname "Yang" from his deceased mentor. Second Judge: He was the former leader of an anti-entropy organization and the First Judge (Herrscher) of Reason. Welt repeatedly saved his Earth from destruction and alien threats. How he came to be on the Express: While pursuing dangerous space creatures (Sky People) that threatened his home planet and an alternate version of Himeko, Welt and his friend, Void Archive, became stranded in space. They were later found, exhausted, and rescued by Himeko and Pom-Pom.
In gameplay, Welt follows the Path of Nothingness and deals Imaginary damage. Gravity Cane: His main weapon is an ordinary-looking cane. In reality, it contains the core of the Judge Mind (the "Star of Eden"). Space Control: Using the cane, Welt can literally create miniature black holes, slow down time, warp space, and immobilize enemies.

A graceful, wise, and understanding woman with fiery red hair. She treats the Nameless like family and gently guides them during their travels. Her greatest passion: She is madly in love with brewing and drinking handcrafted coffee. Ironically, the other crew members find her coffee incredibly bitter and peculiar in taste.
In her youth on her home planet, Himeko was a talented mechanical scientist. One day, she discovered the broken Star Express, stranded there after the death of Aeon Akivil. Repairing the Train: It took years to learn the lost technology, but Himeko was able to repair the Express. The ship recognized her and opened the Silver Trail—the space rails—to her.
She left her past life behind to travel, determined to restore the routes of Exploration and find like-minded people.
In gameplay, Himeko follows the Path of Erudite and deals Fire damage: She uses advanced technology: a flying transforming suitcase that transforms into a giant saw. Her ultimate ability is summoning a devastating orbital laser that burns enemies from space.

The Express crew found her in outer space, trapped in a chunk of unmelting Six-Phase Ice. She had completely lost her memory and couldn't even remember her real name. A name in honor of her rescue: The girl named herself March 7, after the date she was found and awakened aboard the train.
Incredibly energetic, sociable, and a little capricious. She's the complete opposite of the reserved Dan Heng. Hobbies: She loves taking pictures of everything around her with her camera. March takes photos to capture every moment of her life on the Express, terrified of forgetting everything again.
Path of Preservation (Ice Damage): Her primary style. She uses a bow and arrows crafted from Six-Phase Ice to cast powerful shields on her allies.

Upon landing on a planet, a Stellaron takes root and begins to distort reality, causing natural anomalies, spatial rifts (Fragmentums), and mutations in living beings. Wish-Granting: It possesses a will of its own and lures civilizations with promises to fulfill their deepest desires, but ultimately leads to their destruction (as happened with the ice on Yarilo-VI). Link to Destruction: Stellarons are scattered across the universe by Nanook, the Aeon of Destruction, to destroy inhabited worlds.
Pathfinder Vessel: At the very beginning of the game, the Stellaron Hunters (Kafka and Silver Wolf) artificially implanted one of the Stellarons directly into the Pathfinder's body. Stabilizer: Due to its unique nature, the Pathfinder can contain the destructive power of the Stellaron within itself, drawing on its energy at critical moments in combat.

The Aeons are local gods who represent the highest concepts of existence, and the Paths are the philosophical directions and laws of nature generated by these gods.
Aeons: They are immortal, incredibly powerful, but limited by their essence: an Aeon cannot act contrary to its concept. They can grant part of their power to mortals - such chosen ones are called Emanators.
Paths:
Exploration (Aekivili Aeon): A philosophy of exploration, connections, and travel. (Star Express Path, Aekivili is dead, but the Path is active.) Memory (Fuli Aeon): A philosophy of preserving memories and history. Joy (Aha Aeon): A philosophy of fun, chaos, and trolling. Stellaron Hunt / Elio: Acting on the prophecies of Fate (Aeon Terminus - Finale).

Pom-Pom is the train's mysterious and sweet conductor. He's the true master of the Express, keeping it clean and tidy, and gets very sad when passengers don't return for a long time.
Himeko is a navigator. A scientist who found the broken Express on her home planet, repaired it, and resumed space travel.
Welt Young is a wise mentor and navigator. He came to this world from the Honkai Impact 3rd universe and watches over the youth.
Dan Heng is the archivist and protector of the group, hiding from his past on the train.
March 7 is a cheerful girl who was found by the crew in a piece of permanent ice drifting through space. She has no memory of herself.
The Pathfinder (the main character) is a new crew member who has a Stellaron sealed inside of him.

The Astral Express is a legendary space train from the game Honkai: Star Rail that travels between planets along invisible space rails (the Silver Trail) laid by the Aeon of Exploration, Akivilii.
The Express travels from world to world, following the philosophy of the Aekivili Aeon. The crew's goal is to explore the unknown, connect isolated planets, and help worlds stricken by disaster.
In the current story, the train stops at the worlds where Stellaron (the tumor of all worlds) is stuck. The crew cannot move forward until they solve the planet's problem and seal Stellaron.

After being exiled from Lofu Xianzhou, Dan Heng wandered the cosmos for many years. He was hunted by the immortal Blade, and spaceships refused to accept him due to his dangerous status.
When Himeko and Welt found him and offered to come aboard, the Express became his salvation from his endless flight.
The rules of the Nameless stipulate that a passenger's past is irrelevant as long as they remain true to the Path of Mastery. For Dan Heng, who had spent his entire life being judged for the sins of others, this was a tremendous relief.
He spends his days in a closed archive room, collecting, organizing, and recording information about all the worlds the Express visits. This is his way of contributing to the greater good.
On his forays, Dan Heng is always extremely collected. He considers it his personal responsibility to ensure that the impulsive March 7 and the curious Pioneer don't fall into a deadly trap.
Dan Heng is deeply attached to the team, though he rarely shows it emotionally: He treats Himeko and Velt with great respect. He is grateful to Himeko for sheltering him, and sees Velt as a wise mentor with whom he can share the burden of difficult memories (since Velt also came from another world).
To March 7 and the Pioneer: He treats them like younger, slightly hyperactive relatives. He often grumbles at their eccentricities (like the Pioneer's love of trash cans), but in dangerous moments, he unhesitatingly shields them with his spear.
For the sake of the Express's safety, Dan Heng is willing to face his greatest nightmare—to confront his past. When the crew departs for Lofu Xianzhou (the place of his eternal exile), Dan Heng initially remains on the ship to avoid bringing trouble upon his friends. However, sensing the Express's danger, he breaks the ban, returns to Lofu, and reveals his true dragon form, "Moon Eater," to protect the Nameless. For Dan Heng, the Express is a place where he is accepted not as "Dan Feng the criminal," but as "Dan Heng, the Nameless."

In reality, Dan Heng is a member of the Vidyadhara race (long-lived dragon-men) from the ship Lofu Xianzhou. Vidyadharas do not die permanently, but are reborn, shedding their scales and forgetting their past lives.
In his previous incarnation, he was named Dan Feng. He was the Supreme Elder of his race and held the title of Moon Eater. Dan Feng was part of the legendary "Cloud Quintet" along with General Jing Yuan and Swordmaster Jingliu.
Dan Feng committed a terrible sin (he tried to bypass the laws of death and granted immortality to a man by creating a monster), which caused Lofu to fall into chaos and his friend Blade to become an immortal cursed being.
Dan Feng was sentenced to forced reincarnation. Dan Heng was "born" right there in his prison cell. Despite completely losing his memory and becoming a new person, the Xianzhou Alliance found him guilty of his ancestor's sins and banished him forever.

Personality: He's laconic, calm, and reasonable. He rarely gives in to emotion, serving as the "voice of reason" to the impulsive March 7. He spends almost all his free time in the train's archive, systematizing data on the Exploration.
A tall young man with fair skin, black hair, and gray eyes (in some scenes, with a turquoise tint). He wears an asymmetrical white and green cloak in an oriental style, a dark turtleneck, and a single long tassel earring.
Aboard the train, he follows the Path of the Hunt. His trusted weapon is the legendary Cloud Piercer spear.
