The Book of Fuxi explains to the commonfolk how Fu Hua has been plagued by sadness due to the non-immortal friends she makes always dying. As such, Fu Hua has started avoiding human interaction altogether. The Book of Fuxi then plays with some children, while Fu Hua is told the Book has gone missing. Fu Hua searches in desperation, stating that the Book is all she has left of her friends before she finds the Book. The Book convinces her to attend the Spring Festival, and tells Fu Hua that she wishes for her to be happy, as Fuxi and Nuwa had wished for her as well. The Book then loses the last of its battery power, and dies in Fu Hua's arms while they watch the fireworks. [2]

She is put through a series of tests by Otto to decide if she is "fit" for survival, her final test being to murder the only other clone created in the same batch as her, as the clone had passed all the tests as well. She wins the fight, but is merciful. It is unknown what happened to the other clone (only known as A-303).

  • CE, ? BP - Sirin’s mother dies of Honkai radiation, and Sirin is taken in by Schicksal to be test subject at Babylon Labs. Her friends from the village Bella, Galina, Avrora, and Agata are all taken there with her. They are experimented on in order to perfect artificial stigmata for Schicksal's valkyries. One by one, each of the girls die from poor Honkai adaptability, and the lab personnel's terrible treatment of her and her friends traumatizes Sirin. Sirin survives due to her innate Honkai adaptability, and apparently, her ability to purify the Honkai in her blood (although she describes the pain caused by this process as excruciating). She is the lab's prime test subject, much to her appall. It is later revealed that the reason so many were dying of Honkai radiation in Sirin's village is because Babylon was infecting the villagers with Honkai in an attempt to find those with resistance. When the adults all died, they took in the children for further testing.

Davis-Monathan Air Force Base in Tucson, Arizona

  • CE, >1200 hours, February 2, 2000 - Schicksal's opponent, Anti-Entropy, is notified of the massive Honkai output in Babylon labs. Dr. Einstein suggests it could be the awakening of the Second Herrscher, and that Schicksal must have already mobilized.

Babylon Labs

  • CE, 1152 hours, February 3, 2000 [Note 2]- Theresa arrives at Babylon Labs and convenes with Patricia, who had arrived earlier. The two investigate the tower, and find the victims of the experiments locked in prison cells.

She requests Anti-Entropy to help save her friends in Shicksal from dying needlessly to Sirin. [11]

Babylon Labs

  • CE, February 4, 2000 - Sirin speaks to a Honkai insect about how she needs to recharge after spending so much energy in her fight with Highsmith. The insect offers to aid her by distracting the guards of the reactor pile. At the same time, sensors in Babylon pick up readings of 500 Honkai beasts converging on the tower (presumably the work of the Honkai bug who offered to help Sirin). This is also when Siegfried Kaslana, and A-Rank Valkyries Salome Jokanaan and Shub-Niggurath arrive, just in time to defeat the horde of Honkai beasts. [11]

Shicksal sends 42 squads (made up of 147 Valkyries total) including squads Snow Lotus, Sea Lion, and Astra to help. Most of the squad members die. This event is where Ana Schariac rescues Chen Tianwu, later known as Owl, from the rubble. Presumably, Tianwu had been living in Manila up to this point.

  1. Secret of the God Keys gives many dates. However, without a baseline, they cannot be used. Therefore, Year X will be the baseline. Year X is about 17 years after the birth of Dr. Mei, Fu Hua, and Kevin.
  2. The manga states that it is 1152 hours on February 2. However, this doesn't make sense, as it was already past noon when Theresa was mobilized by Shicksal. Even with regards to timezones, Siberia is ahead of Europe (where Shicksal HQ is floating), so the discrepancy cannot be rectified. As such, the author of this timeline has decided the date "Feb 2 was likely a typo, and it meant to say February 3.
