The Nexus
Officially described as the fundamental connections between all things. It is the binding fabric of the world before the cataclysm.
The Nexus and the Sundering
The Sundering
A cataclysmic event that broke the Nexus and severed the stable connections between the Aspects. CONFIRMED by official @HonkaiNA posts.
The 81 Planes
The fragments left by the Sundering became 81 separate universes, called the Planes. CONFIRMED. (The figure of 81 is official; the often-quoted "81 Aspects, one per Plane" lines up with it but is not separately stated.)
The Old World and the New World
Old World — paired Aspects & Sovereigns
Before the Sundering, Aspects existed in opposed pairs, and the Old World was governed by rulers called Sovereigns, each tied to a pair of opposing Aspects. CONFIRMED framing; the exact total of Sovereigns (a "39" figure circulates) is community-sourced and unconfirmed.
New World — singular Aspects & Novarchs
After the Sundering, each of the 81 Planes is ruled by a Novarch embodying a single Aspect. The figure of 81 Novarchs lines up with the 81 Planes; specific Novarch numbering is from press/community fiches.
Aspects
Officially named pairs
HoYoverse has explicitly named the opposed pairs Light/Dark, Life/Death and Love/Hate.
Corroborated through rulers
Order/Chaos, Reality/Illusion and Infinity/Finity are corroborated through revealed Sovereigns/Novarchs (e.g. an Order/Chaos ruler), but not stated as a tidy list. War and Strength are referenced as Aspects in press coverage (Strength via the Anima Fyrklor).
Community-tracked full set
A complete set of eight pairs and a fixed Aspect count circulate on community wikis. Treat these as unofficial until HoYoverse publishes the full taxonomy.
World-Ender, Sovereigns & Novarchs
The World-Ender
An antagonist entity linked to the Sundering. Its existence is corroborated through revealed Sovereigns (one is described sealing it, another making a pact with it). REPORTED.
Victus
Described as the first Sovereign, tied to Order/Chaos, who became a Novarch of Order in the New World. He is said to have defeated the World-Ender repeatedly — the official phrasing is "countless times"; a specific "seven times" figure is community-sourced and not reliable, so it is not stated here as fact.
Iia — the seaside hub
Iia
A seaside-town Plane that serves as a hub. Beta coverage named the Kakatini Grand Hotel, a Pedestrian Street and Fleming Tower within it. CONFIRMED as a hub; the venue names are from beta press coverage.
The Amphitheater & Grand Championship
Sir Champion, the Novarch of Competition, organises the Grand Championship of Nexus Battles in the Amphitheater — a goal Animasters compete toward. REPORTED by a single outlet.
Returning Honkai characters
Kiana
From HI3rdKiana Kaslana (Honkai Impact 3rd) appears as a Planestrider — a traveller across the 81 Planes — and is shown with the companion Anima Puddlipup. She was the face of the game's tease at the Honkai: Star Rail 2nd Anniversary concert (May 2025). A "Kardia" role label circulates from a single channel and is not fully corroborated.
Blade
From HSRBlade (Honkai: Star Rail) appears as the 22nd Novarch, "The Peak," searching for a missing Sovereign. REPORTED across multiple outlets.
Kafka
From HSRKafka (Honkai: Star Rail) is referenced as one of the Old-World Sovereigns who went missing after the Sundering, per beta coverage. REPORTED.
What is still unconfirmed
Treat these as community-tracked, not canon
A precise count of Sovereigns ("39"), Victus's exact number of victories over the World-Ender ("seven"), named factions such as a "Committee for a Joyful Iia", the "Aspect Fracture" concept, and the "Kardia" role all trace to single community/wiki sources. They are recorded here as leads, not confirmed lore, and will be promoted only when an official source corroborates them.
