The Golden Halos is a Loyalist Space Marine Chapter of unknown Founding and origin. Almost nothing is known about this Chapter in the Imperial records other than that it was engaged in such notable campaigns as: Kistvaen, Podzul, and the decades-long Siege of Nectocalyx, which was colloquially referred to as "The Meatgrinder". Its motto Ex Ungue Leonem ("Judge the Lion by his claws") reveals its proud martial tradition.
- Garandus Incident (322.M41) - When a vessel appeared out of nowhere, it was positively identified as the "ghost ship", the Celestion, a doomed vessel that disappeared in the Warp nearly a century earlier. This was the second sighting of the mysterious vessel, which was dramatically encountered by the Imperial Battlecruiser Garandus, when the vessel appeared out of nowhere and collided against the Imperial vessel. Several of the hangars containing the Golden Halo Space Marine Chapter's dropships were ripped apart. The force of the void sucked many of these vessels out into the Warp. As the crew proceeded to make repairs on their stricken vessel, and retrieval of the unmanned dropships was underway, the Navigator alerted the Captain that the gravitational pull of a forming vortex became greater than the reduced power of the Imperial vessel's engines. There was nothing they could do to prevent the Garandus being sucked inexorably to its doom. It was only because of this accident that a greater disaster was avoided. If the Garandus had not been forced to alter course and reverse engines as a result of the Celestian's appearance, it appears fatal contact with the rapidly appearing vortex would have been unavoidable. Nevertheless, the mission had to be terminated. Casualties were listed as 2,362, 17% from the Golden Halo Space Marine Chapter.
The Golden Halos Chapter primarily wears ebon Power Armour. The colour of the Aquila or Imperialis on the chest plate as well as the shoulder plate trim and helm is gold. The open-faced golden squad specialty symbol -- (Tactical, Assault, Devastator or Veteran -- is located on the right shoulder plate. A golden Gothic numeral is centred on the squad specialty symbol, indicating squad number. The iconography on the left knee plate indicates company number in accordance to the Codex Astartes -- i.e. White (1st Company), Yellow (2nd Company), Red (3rd Company), etc.
The Golden Halos' Chapter badge is a golden circle with a golden halo surrounding it, on a field of black. This symbolism represents their namesake, the Golden Halo.
