Kor'bhan Octarius

Sixth Princeps Kor'bhan Octarius, the ' Black Kraken '</nowiki, is the current commander of the Argent Leviathans Space Marine Chapter's 6th Company.

Background
Sixth Princeps Kor'bhan Octarius was the Captain of the Argent Leviathans Chapter's 6th Company from M41.578 to M42.034 (prior to Primaris reinforcements). Octarius was known for being unusually kind for an Argent Leviathan, this earned him the mocking title of the 'Black Kraken', Octarius, however, took this in stride and adopted it as the sigil for his Company. Once the Great Rift opened, the 6th Company of the Argent Leviathans was one of the four companies that were left stuck within the Imperium Nihilus.

During this tumultuous era, Kor'bhan spent his time protecting the Caerulian system from Chaos Warband and Daemon incursions. However, once Caerule was assaulted by a Slaaneshi Daemon force led by the Keeper of Secrets Vro'nan Pyredancer, Octarius managed to successfully get 253 Astartes and 1 million Caerulian citizens off-planet before him and the Sixth company were entirely wiped out by the Daemon forces.
