The Octarius Sector is a region of space in the Ultima Segmentum, roughly the size of Ultramar, and it’s home to the Ork Empire of Octarius. It matters because it’s the site of a massive war between Orks and Hive Fleet Leviathan, a conflict so dangerous the Imperium has quarantined the entire area.
Overview
It’s a sector of space in the Ultima Segmentum, and it’s the territory of the Ork Empire of Octarius. The empire is huge, spanning an area almost as large as Ultramar.
The sector is defined by the Octarius War, an ongoing conflict between the Orks and Hive Fleet Leviathan. Because of that war, the Imperium keeps the sector under quarantine, a blockade known as the Cordon Impenetra.
Key worlds and systems
The sector has several sub-sectors, including Pankallis, Greygar, and Heingaard. The Margus System is also within its borders.
The central planet is Octarius itself, an Ork world with a single mega-continent and large snowy peaks. Its ruler, the Overfiend, has a shanty capital called Gargates. Depending on the source, the planet is also called Octaria or Octavius.
Other notable planets include Sigma-Ulstari, a Forge World, and Dakka, a scrapworld infested with Ork-Genestealer hybrids. Several worlds, like Orrok, Ghorala, Derragon, and Keltor, have been consumed by Leviathan.

The Octarius War
The war started when Inquisitor Kryptman redirected Hive Fleet Leviathan into the Octarius Sector, hoping the Orks and Tyranids would wipe each other out. Instead, it sparked one of the largest battles in the galaxy.
The fighting began on Octarius. Orks cheered as Mycetic Spores fell, eager for a fight. The skies filled with Gargoyles, Deffkoptas, and Fighta-Bommers. Genestealers burst from tunnels, and Lictors silenced gun emplacements. The war soon spread across the entire sector.
In the end, the Swarmlord led a massive push and killed the Overfiend, allowing Octarius to fall. The planet was consumed by the Tyranids.
