The Knights of Eternity was a Loyalist Space Marine Chapter of unknown Founding and origin. Almost nothing is known about this Chapter in Imperial records. In 990.M41, Hive Fleet Kraken attacked across a large front of Imperial space that covered many thousands of light years. Several Space Marine Chapters dedicated their forces to saving the worlds that other Imperial armies had abandoned. The Knights of Eternity were one of those Chapters, selling their lives dearly in the defence of the Imperium against the predations of the Great Devourer. They are presumed to have been completely obliterated.
The Knights of Eternity primarily wear white Power Armour, which includes the chest plate, torso, groin and legs. The power pack, helm, shoulder plates and arms are red. The shoulder plate trim is black. The Aquila or Imperialis on the chest guard is dark yellow. The white squad specialty symbol -- Tactical, Devastator, Assault or Veteran -- is located on the right shoulder plate. A red Roman numeral is stenciled in the centre of the squad specialty symbol, indicating squad number. The colour of the left knee guard indicates company number in accordance with the Codex Astartes -- i.e. White (1st Company), Yellow (2nd Company), Red (3rd Company), Green (4th Company), etc.
The Knights of Eternity's Chapter badge is a stylised, open-faced "I" symbol. A large white skull is superimposed over an open-faced, white roundlet -- centred in the middle of the main icon, on a field of red. This iconography is reminiscent of the Knights of Eternity's namesake -- as eternal protectors of the realm of the Imperium -- only in death, does their duty end.
