Fractures

A Fracture, also known as Fractures, is a piece of Halo fiction considered part of a different "branch" of Halo lore to the normal Halo universe. They are divergent universes or timelines that still share a variety of elements in common with core canon.

Tenrai
The Tenrai Fracture 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: Yoroi.

Belos
The Belos Fracture is inspired by 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.

Blackguard
This Fracture branch has Blackguard armor in it.

Drengr

Production notes
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.
