The Lost and the Damned
From Lexicanum
The Lost and the Damned are not a single coherent force, but rather a diverse and infinite collection of warbands and hosts gathered by Abaddon the Despoiler to support his Black Crusades against the Imperium. The Marines corrupted by Horus in the depths of time are an elite faction of the Chaos armies, the vast and blighted majority is formed by these lesser servants of the thirsty Gods.
There are populated worlds in the Eye of Terror, accursed places of unimaginable horror. The twisted and enslaved populations of these world form the bulk of The Lost and Damned hosts. Brigands, heretics, cultists and mutants who have fled from Imperial space into the Eye of Terror can also be found marching beneath the banners of Chaos.
Occasionally entire companies, or even regiments of Imperial Guard turn to Chaos, and take with them their vehicles and armoury. These faithless traitors take with them the discipline and training of Guardsmen, forming a hardened and reliable core amongst the slavering hordes of the Lost and Damned.
Fighting alongside these mortal servants of the Dark Gods are the Daemons of the Warp, summoned by blasphemous rituals and the spilling of blood. These are a force that few can withstand, for dread and despair proceeds them, and they fight with unnatural strength and speed.
Leading these hosts into battle are the mighty Aspiring Champions - Space Marines who betrayed the Emperor ten thousand years ago during the Horus Heresy. These power hungry individuals have departed from their Legions to gather hosts of mutants and traitors, as they endeavour to carve out their own dominions in the Eye of Terror. However, when Abaddon leads a Black Crusade they will put aside their petty wars and rivalries for a common cause.
When engaging the Lost and the Damned, Imperial commanders will be assaulted by a tide of filth and blasphemy that attacks again and again, regardless of its losses, with seemingly inexhaustible numbers. Such a foe is unnerving to face, even for hardened veterans, and disease and madness precede the advancing hordes. These assailants can be by anything from shambling hordes of animated corpses, to Traitor Guardsmen still bearing Imperial insignia on their blood streaked armour.
