Fulgrim: Visions of Treachery

Fulgrim felt a massive swell of power fill him as he drew the sword, its blade rippling with afterimages 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.
