'I will not listen to you!' roared Fulgrim, drawing his sword. Eldrad staggered as though a sudden force assailed him. The farseer's dark eyes flashed to the blade and his features twisted in an expression of horror and anguish.

'No!' cried Eldrad, as a great wind that seemed to rise from nowhere howled around the stunned observers. Fulgrim's blade swept out towards Eldrad's neck, cleaving the air in a sweeping, silver arc.

A fraction of a second before the sword took the farseer's head an enormous blade flashed and intercepted its deadly edge. An explosion of sparks burst before Eldrad and he staggered away from Fulgrim as the wraithlord stood erect, its huge sword drawing back to strike at the primarch.

Eldrad shouted, 'They are corrupted! Kill them!'

Fulgrim felt a massive swell of power fill him as he drew the sword, its blade rippling with after-images of vibrant purple energy. His Phoenix Guard and captains surged to their feet as he struck his blow against the farseer, and guns blazed as a vicious, short range firefight erupted.

The bone-armoured warriors charged with an ear-splitting shriek that tore at the nerves, and a hail of bolter fire cut down a handful before they hit home. Fulgrim left the warriors to his captains, as the Phoenix Guard charged the mighty, golden-helmed wraithlord.

You must kill him! The farseer must die before he ruins everything!

Fulgrim roared as he leapt after the farseer, the wraithlord's monstrous sword arcing towards him as the Phoenix Guard slashed at it with their golden blades. He rolled beneath the blow, rising to pursue the architect of this bloodshed. Eldrad Ulthran and the grim-faced warriors in black armour backed away from him towards the curving structure, as a pale nimbus of light began to gather at its base.

'I tried to save you,' said Eldrad, 'but you are already the unwitting tool of Chaos.'

The Primarch of the Emperor's Children swung his sword at the farseer, but his enemy vanished in a flare of light and his weapon clove only air. He roared in frustration as he realised that the structures were in fact teleportation devices.

He turned back to the battle raging behind him as a hail of energised bolts spat from the barrels of the nearest skimmer tank's guns. Its first shots had been hesitantly aimed, thanks to the presence of the farseer, but Fulgrim saw that no such caution restrained them now. The prow of the tank skimmed the grass as its pilot brought it around in a tight turn, expecting his quarry to flee, but Fulgrim had never run from an enemy in his life and wasn't about to start now.

Fulgrim leapt into the air just as the eldar pilot saw the danger and tried to gain height. It was already too late. The primarch's sword hacked through the side of the vehicle and tore downwards, ripping through its hull as he gave a bellow of hatred.

The tank's pronged front section dropped to the ground and the vehicle slewed around, the bevelled edge carving into the ground, flipping the vehicle over onto its side with a terrific crack of what sounded like splintering bone.

Bright energy exploded from the wreck in a huge plume of light, and Fulgrim laughed in triumph. He spun his sword and returned his attention to the clash of weapons, watching as the terrifying wraithlord reached down and crushed one of the Phoenix Guard in a massive fist. Armour cracked asunder and blood fell in a crimson rain as the warrior died. Fulgrim snarled in anger as he saw three of his elite praetorians lying twisted and broken at the machine's feet.

His captains fought with the warriors in bone armour, their swords a blur as shrieking war shouts filled the air over the ring of steel on bone. Fulgrim moved away from the blazing wreckage of the tank, his sword aimed at the gold-helmed war machine.

As if sensing his presence, the wraithlord turned its head towards him and hurled aside the dead warrior in its grip. Fulgrim could sense the ghost within the machine as a blazing hunger for vengeance and knew this thing wanted him dead as much as he desired to see it destroyed.

With a speed that shocked him, the wraithlord loped towards him, its agility terrifying. He stepped to meet it and ducked beneath a scything blow of its crackling blade, rising again to hack his sword into its slender arm. The blade bit a fingerbreadth before sliding clear, and Fulgrim felt the jarring vibration of the impact along the entire length of his body. The wraithlord's fist slammed into his chest and punched him from his feet, the eagle stamped breastplate cracking under the thunderous blow. Fulgrim granted in pain, tasting blood on his lips.

The pain was enormous, but instead of laying him low it energised him, and he leapt to his feet with a wild cry of exultation. His wreath hung broken over his face and he ripped it clear, tearing out his plaits and smearing the powder and oils across his face.

Looking more like a feral savage than the Primarch of the Emperor's Children, Fulgrim once again launched himself at the wraithlord. Its huge sword slashed towards him, but he raised his own blade and the two met in a ferocious thunder of metal and fire. The purple gem in the pommel of Fulgrim's sword flared, and the wraithlord's blade exploded in a shower of bone fragments.

Fulgrim pressed his attack as the wraithlord reeled, and swung his sword in a murderous, two-handed swing at its legs. He roared as the blade smashed into its knee and tore through the joint with a shrieking howl of pleasure. Rippling coils of energy whipped from the wound as the great war machine swayed for the briefest moment before crashing to the ground.

Now finish it! Destroy what lies within its head and it will suffer a fate beyond death!

Fulgrim leapt on top of the straggling machine, smashing his fist into the smooth sheen of its golden face with a deafening war cry. The surface cracked and split under the force of his blow and he felt blood spring from his hand. He ignored the pain and hammered his fist against its head again and again, feeling the surface of the machine's carapace-like skull yield to his furious assault. It tried to reach up and hurl him from its body, but he lashed out with his sword, the blade hacking off its huge fist with an ease that had seemed impossible only moments before.

At last the golden helm cracked and Fulgrim tore the wraithlord's head open, revealing a smooth ceramic faceplate, pierced and woven with gold wire and engraved with silver runes. Its surface was studded with gleaming gems, and at the centre of this arrangement sat a pulsing red stone. Fulgrim could sense the fear emanating from this stone and reached down to pluck it from its mounting, a rising shriek of panic felt in the soul rather than heard. The stone was hot to the touch, and fiery lines danced within its depths, haunted shapes and alien features writhing within it.

He felt its anger and hatred towards him, but most of all he felt its dreadful, all-consuming fear of oblivion.

Fulgrim laughed as he crushed the stone in his fist, hearing a shrieking howl of anguish flee its destruction. He felt his sword grow warm, and looked down to see the gem at its pommel burn like an amethyst star, as though feeding on the spirit released from the stone.

How he knew this he did not know, but next to the elation he felt in victory, it seemed a minor mystery, and no sooner had the realisation surfaced than it was gone.

As the wondrous feeling of power faded, Fulgrim turned his face towards the battle being fought by his captains. They struggled against the shrieking warriors in bone armour, their swords fencing in a deadly ballet with these supremely skilled warriors. Behind them, the remaining enemy tank waited to support its fellow eldar, its guns useless while the combat raged.

Fulgrim raised his sword and charged.
