The Ork Empire of Octarius was one of the largest Ork domains ever seen, a sprawling sector-sized empire in the Ultima Segmentum. It became the site of a brutal three-way war that bled the Orks, Tyranids, and Chaos forces, and ultimately shattered the empire when its capital fell.
What was the Ork Empire of Octarius?
The Ork Empire of Octarius covered the Octarius Sector, a region almost as large as Ultramar. It was centred on the Ork World of Octarius (also called Octaria), a mountainous planet with a single mega-continent. The empire was ruled by a warlord titled the Overfiend of Octarius, and its Orks likely belonged to the Blood Axes clan.
For a long time it was a typical Ork realm: constantly fighting, constantly growing, and largely ignored by the wider galaxy. That changed when Inquisitor Kryptman deliberately redirected Hive Fleet Leviathan into the sector.
The Octarius War
Kryptman’s gambit was to pit two existential threats against each other. The result was the Octarius War, a meatgrinder that consumed worlds and billions of lives. The Overfiend marshalled his tribes and met the Tyranid invasion head-on. The fighting was apocalyptic, with Ork anti-air guns filling the skies with Tyranid flesh and Genestealer broods erupting from the ground.
After the Great Rift formed, Khornate forces invaded as well, turning the conflict into a three-way brawl. For a while, neither side could gain the upper hand. But then the Swarmlord launched a massive push on Octaria itself. After a gruelling campaign, the Swarmlord killed the Overfiend, and the capital was consumed by Leviathan.
Known worlds of the empire
The empire encompassed many worlds, most of which were consumed by Hive Fleet Leviathan. Only a few are named in Imperial records. The table below lists some of the key planets and their fates.
| World | Status |
|---|---|
| Octaria (Octarius) | Capital; consumed by Leviathan after the Overfiend was slain |
| Orrok/Orruk | Consumed by Leviathan |
| Urmuk | Junka-Port; consumed by Leviathan |
| Dakkazot | Largely consumed by Leviathan |
| Badsquig | Largely consumed by Leviathan |
| Ghorala | Consumed by Leviathan |
| Derragon | Consumed by Leviathan |
| Keltor | Consumed by Leviathan |
| Ghubelia | Site of Genestealer infestation |
| Kraidak | Invaded by Leviathan |
Aftermath and legacy
With the Overfiend dead and Octaria lost, the empire fractured. Multiple Warlords now fight to become the next Overfiend, and the sector remains a war zone. The Octarius War continues, but the Ork Empire of Octarius as a unified force is no more.
The war’s outcome is still uncertain. It’s possible that the Tyranids will eventually consume everything, or that the Orks will adapt and rebound. Either way, the sector is a perfect example of the grim darkness of the 41st Millennium: a desperate gamble that only made things worse.
