Events from Honkai: Star Rail 2.4 and 2.5 saw Borisin's secret invasion of Xianzhou Luofu to free their ringleader, Hoolay, from Shackling Prison. This story focuses primarily on the conflict between the Borisians and their relatives, the Foxians. However, it also touches on the centuries of wars between the Xianzhou Alliance and the main faction that Borisin is a part of: the Denizens of Abundance.
Denizens of Abundance includes the long-lived species that follow Aeon Yaoshi, which include:
- Borisin: These dog-humanoid species share a common ancestor with the Foxians, and both once lived on the planet Verdantia. It is said that Yaoshi created the Redspring in Verdantia and those who drank from it gained immortality. This blessing also caused a population boom in it, leading to its collapse. The survivors fled the planet, and the Borisins eventually made a name for themselves by conquering other civilizations with their brute force and immense knowledge of biotechnology.
- Wingweavers: These are feathered species that formerly lived on Muldrasil. They were enemies Honkai: Star Rail's Xianzhou because before the latter gained immortality. They killed many Alliance natives.
- Houyhnhnm: These centaur-like species have four hind limbs and two arms. They formed an alliance with the Borisins and were recently enslaved by the Antimatter Legion.
- Heliobi: These are formless forms of pure energy. Their origins are unknown, and while Xianzhou classifies them as Dwellers of Abundance, their faction affiliation is unclear. They have been enemies of the Alliance since time immemorial, as they often attempt to control and drain human bodies.
Conflict between the Denizens of Abundance and the Xianzhou Alliance
Loyalty to the inhabitants of their path makes them natural enemies of the Xianzhou, whose purpose is to eradicate the “Plagues of Abundance”. To understand this conflict, we need to know the history of the Alliance, who were formerly devoted followers of the Way of Abundance.
Xianzhou history and abundance
Centuries ago, the Xianzhou Alliance sought the medicine of immortality and received it from Yaoshi through the Ambrosial Arbor that Aeon planted on Luofu. However, they found that the long life they sought and now enjoyed was a curse, as Xianzhou's oldest citizens ended up being “Mara-Struck”. This condition causes a long-lived species to slowly lose their sanity and develop painful growths on their bodies that irreversibly transform them into hostile beings.
Immortality also caused massive population growth in Xianzhou, which was mismanaged and resulted in civil wars. The fleet suffered from attacks by aliens who wanted immortality for themselves as well. Reignbow Arbiter Lan, one of the Alliance's fiercest heroes, tired of the bloodshed and civil unrest, rose up against the Abundance's control of Xianzhou.
The Denizens of Abundance Wars
Not everyone supported Lan's dissent. However, the Alliance soon called for help as the Wingweavers began advancing towards the Xianzhou fleet. The hero made a deal with Flint's Emperor of Heliobi, who was imprisoned in Shackling Prison, to harness their power. Together they fired an arrow that destroyed the Ambrosial Arbor and the invading Wingweaver army in one shot. The power of this attack was so strong that it damaged every ship in the Xianzhou fleet. Lan and the Flint Emperor then ascended to divinity and became the Aeon of the Hunt.
Following the events of the First War, the Denizens of Abundance Alliance swore allegiance to Lan. Their mission to destroy the Denizens of Abundance led to two other major conflicts. The most recent one ended up killing hundreds of thousands of Xianzhou pilots. Almost three decades have passed since the third war, and it looks like the Borisin invasion could trigger the next one.
