The champions of Plufestea are a renegade chapter. They were once known as the Blue Hands, an Ultramarines successor chapter. During the battle for Armageddon, they began to dabble in the dark arts in order to gain the upper hand against a tide of Orks. At first, the marines promised each other that the magic they used was a means to an end to gain victory against the Orks, but gradually they succumbed to the temptations of the dark gods. The ruinous powers granted them many victories, and by the time they had left Armageddon, they had become fully-fledged worshippers of chaos.

Upon their return to their homeworld, the fortress world of Plufestea, they spread the vile promises of the warp to the inhabitants, and slowly the entire planet became devoted in the worship of chaos, with cults of Tzeentch, Slaanesh and some of the minor gods occurring around the planet.

The warband is currently led by Krebus, a mighty sorcerer of Tzeentch. He rose to prominence when he used his psychic powers to defeat Inquisitor Gryaznov. Gryaznov had secretly observed what had happened on Armageddon but refrained from revealing what he knew, since the Blue Hands were successfully holding back the Xenos tide. Once the battle was over, Gryaznov sent spies to observe what happened on Plufestea. When he realised that the planet was doomed, he attempted to organise an orbital bombardment to raze the planet’s surface. However, before the message reached the nearest Imperial fleet, Gryaznov’s ship was ambushed by a ship commanded by Krebus. Krebus has received visions from Tzeentch about impending doom, and tried to convince the warband’s hierarchy that the danger was real, but to no avail.

Knowing that without action, they would all perish, Krebus had stolen a cruiser and ordered the crew to follow his vague directions. Gryaznov’s forces were overwhelmed by hordes of fanatical cultists. Eventually Gryaznov sought out Krebus and challenged him. The two fought, sword against sword, with neither gaining the upper hand. Eventually, Krebus, sensing that the fight was going nowhere, allowed Gryaznov to wound him. He retreated to a dark corner, cursing the Inquistitor. As the Inquisitor spoke into his vox to call for backup, Krebus began to chant a ruinous spell, summoning all the powers of Tzeentch. He unleashed a torrent of blue flame from his eyes that spread around the surrounding corridors, incinerating Gryaznov and those who had come to his aid in the most agonising fashion. Leaderless, the inquisitorial troops were quickly routed by the followers of Krebus. Krebus returned to Plufestea with both cruisers, revelling in his glory.
