At some point during their sojourn in the Eye, the Lances of Pteros were corrupted by Nurgle, becoming the Lords of Decay, and latter absorbed into the Death Guard Traitor Legion.

This Chapter hails from the world of Outrenacht.

These are used to perform surgical strikes or seize strategic points with the aid of fast-moving Razorbacks or Rhinos. Like its fellow Chapters the Angels of Fury and the Raven Guard, the Legion of Night has forged its combat doctrine around such highly mobile insurgent tactics.Legion of the DamnedFire Hawks21st FoundingThe Legion of the Damned is the most famous of the Chapters of the 21st Founding, known as the "Cursed Founding", and was once known as the Fire Hawks.

Many claim to have seen these living spectres in battle, but no thanks can ever be given to them, for they leave as suddenly and as quickly as they appear.LibatorsUltramarinesSecond FoundingThe Libators is a Codex Astartes-compliant Space Marine Chapter which is a Second Founding Successor Chapter of the Ultramarines.LiberatorsUnknownUnknownThe Liberators is a Codex Astartes-compliant Space Marine Chapter of unknown origin and Founding.Lion WarriorsUnknownUnknownThe Lion Warriors is a Codex Astartes-compliant Space Marine Chapter of unknown origin and Founding.Lions AzureUnknownUnknownThe Lions Azure is a Loyalist Space Marine Chapter of unknown Founding and origin.Lions DefiantUnknownUnknownThe Lions Defiant is a Loyalist Codex Astartes-compliant Space Marine Chapter of unknown Founding and origin.
