Crimson Sabres - Twisted Beyond Recognition: Planet by planet, the Crimson Sabres worked their way ever more deeply into the Eye of Terror. They slaughtered their way through Chaos Cultist scum with ease, but were slowed considerably when they ran up against Renegade Chaos Space Marine warbands. Through their own numbers, the power of their fleet and the anger in their hearts, they pressed on.During one planetfall, the Crimson Sabres fought Khornate Berserkers, toppling their blood-dripping idols and gunning down the red-robed Chaos Cultists that surrounded them. On a beslimed and marsh-ridden moon they discovered the lair of creatures that walked like men, but had the heads of enormous insects, with great bulbous compound eyes. Some of them, ominously, wore the power armour of some unrecognisable Space Marine Chapter.All were dispatched with the same ruthless efficiency that marked every one of the Crimson Sabres' actions. After each battle, the voices were silenced and each of the Crimson Sabres felt renewed and full of worthy purpose. Slowly, however, the haunting voices returned, building into an ever more maddening cacophony. During the long Renegade Wars, there was no single moment that marked the Chapter's turn to Chaos, rather it was a gradual evolution. The flowing powers of the Warp and the heightened fears and desires of each Space Marine combined to morph the Crimson Sabres.In some, the changes were internal or too subtle to be noticed, in others the transmutation was far more drastic. No one knew when Chaplain Okrark's tomes of liturgies altered, but his zealous speeches shifted from spouting the righteousness of sacrifice and the Imperial doctrine to the pursuit of power, the rights of the individual, and the almighty strength they bore within their own band of warriors.One Space Marine's eyes glowed crimson as he grew angry, another noticed his teeth growing into more pronounced fangs. Others returned from battle to discover that their own bones had grown forth, penetrating their armour to form new ridged designs. Great horns sprouted out of helms, growing in size and elaboration to match their owner's valour and deeds of battle.None were so large or as formidable as those of Chapter Master Kranon. On the ever-changing mist world of Drabloyn, esteemed Sergeant Draznicht's strange new precognitive powers erupted forth, as did the third eye that grew out of his forehead.Space Marines are trained to accept alterations to their bodies. In part, this has to do with the extra organs implanted within them during the genetic modification stages of their early development, but largely it has to do with their war-filled lives. Typically, a Space Marine warrior will sustain more wounds in a standard year than any two dozen frontline Imperial Guardsmen, and in his lifespan he will have recovered from many injuries that would have killed an unmodified man outright.Such rugged survivability is not without cost, and scars, burns, or losses of limb are common. Witnessing gruesome wounds, or bionic replacements, is just another part of being a Space Marine. Perhaps this attitude made them so readily accept the new growths upon their bodies? When they entered the Eye of Terror, they had already chanted their death hymns, already rationalised that this was their last campaign. From that stance, what matter if a Space Marine grew an extra appendage or sprouted razored talons? If these new mutations aided the slaughter they wreaked upon their foes, then so much the better.
