This article is about the non-canon spinoff universes known as "Fractures". For the short story anthology, see Halo: Fractures.
Fractures are reinterpretations of the Halo universe, akin to alternate universes, that exist separately to the core canon of the franchise. They are designed to maintain the main elements and themes of the Halo universe, but are markedly divergent due to either fundamental differences in the nature of the setting, or the way certain events play out. Fractures are designed to give fans a unique and fresh take on the Halo universe, while leaving the existing lore untouched.
Fractures universes are used to lend background lore to otherwise non-canonical in-game elements, such as the Yoroi core in Halo Infinite or Belos, Blackguard and Drengr armours in Halo: The Master Chief Collection. As such, they are often linked to in-game events, such as MCC's Season 8: Mythic or Infinite's Fractures: Tenrai event.
The Tenrai universe is inspired by Samurai and Japanese culture. In this universe, the 343 clans of the Imperial Court once feuded with each other for generations, but united in the face of an invasion by the Covenant. To defeat the invaders, the clans pooled their knowledge and crafted a new type of armor for their samurai warriors; known in Halo multiplayer under the name Yoroi.
The Belos universe is inspired by classical Greek and Roman culture. In this universe, the Chosen are humans who have been chosen to undergo augmentations, making them almost demigods among humans. As such, Chosen make up commanders and bodyguards within the armies sworn to defend Lacedaemon. The Chosen are armed and equipped with custom-made sets of mythic armour and weaponry; known in Halo multiplayer under the name Belos armor.
The Blackguard universe is inspired by feudalism and Medieval European culture. In this universe, the Blackguard are knights and renegades who don the Blackguard armor acting as knights, protectors, and thieves in the universe. The Blackguard are equipped with specialised armor for whatever kingdom they come from, with weapons that civilians admire and fear; known in Halo multiplayer under the name Blackguard armor.
The Drengr universe is inspired by Norse culture. In this universe, the Skalds are warriors and storytellers who collect many stories as they fight against the Shapeless Horrors. The Skalds being true warriors and intelligent story tellers with a quick wit and a sharp tongue they would need a weapon against the Shapeless Horrors they would need runeplate; known in Halo multiplayer under the name Drengr armor.
The following is a list of in-game events that are themed around Fractures universes.
Halo: The Master Chief Collection
Halo: MCC has only featured one Fractures-themed event:
Halo Infinite was the game for which the concept of Fractures was first introduced, as a way to expand the cosmetic customisation options beyond those that would exist within the main Halo universe. Thus, it is expected to feature many Fractures-themed events:
Fracture are used as events in Halo Infinite and Halo: The Master Chief Collection to explain the existence of certain armor models, such as Yoroi and specific Season 8: Mythic items, in their relevant games.
