Erex took a moment to gaze upon the horror etched into the Guardsmen's faces. His smile revealed fierce rows of pointed teeth. He lashed out at the sergeant; his claws tore into the man's chest and lifted him above his men while his other weapon caved in the head of another. He threw the limp soldier over his back as he laid into the rest of the squad with crozius and claw. A bolt of fire burst from his clawed hand incinerating one who tried to flee. He swept his claw in a wide arc, still trailing flame, the heat melting the flesh of the Guard. The guard were trying to flee over the tops of the trenches but they were cut down by cursed flames hurling over Erex's head. He dug his claws into the wall of the trench and hauled himself up where he could see his prey. He knew where he could be found, the coward leading the pitiful humans against his warriors. Erex stretched his wings, taking in the power of the Mutator and closed his eyes. His spirit form raced forwards passing through the walls of the bunker to come to stand before the commander. His spirit took the form of a great angel of death cloaked in shadows, before his Blessed the assembled humans with the gift of his Lord and Master. His spirit rushed back to his body to see his handiwork with his true eyes, all eight of them. Mutated flesh burst from the portholes of the bunker before it exploded outwards, the massive spawn roaring with a dozen tortured voices before it tore its way through the artillery that tried to keep his warriors down. Now freed from the bombardment his warriors raced forward to slaughter the Guards, voicing Praise to Great Tzeentch and his Champion Selunax. Lord Selunax stood atop a mound of bodies his body three times taller than Erex's and he was already a giant among the Disciples. Four great wings sprouted from his back, and arcane energies spun around his form. His legs were avian and his face was crowned by feathers and a pair of horns had a sphere of flame held at their apex. In his hands he held a giant lance, as much a weapon of close quarter combat as is it was a conduit for the energies of the warp. Bolts hurled from the weapon to tear the bunkers asunder and mutate the Guard that were in the open. Erex knew that he couldn't fail his God while he served under such a chosen warrior and he hurled a bolt of warp flame from his hand to blast apart a sandbag wall and burn those who cowered behind it.

'For the Great Lord Tzeentch, the One who granted you these great gifts. You will not fail under His gaze!'

The Disciples roared in agreement and they enjoyed in their slaughter. An entire generation died this day and Erex's broken face smiled as he felt his skin toughen and bony protrusions pushed through his chest plate. The mind of Selunax touched his and he looked up to the sky, seeing the telltale contrails of Space Marine drop pods blazing down from the heavens.

Legate, break their spirit.

'Executor, to me!'

Executor Barbas followed the Legates gaze and threw aside the ruined body of the Guardsman he was pummelling into the ground. His bestial face panted and his took his place beside Erex. In one massive hand he wielded a green glowing black blade; his terrifying tool used in rituals of summoning and warp travel. One of the Drop Pods slammed into the ground nearby, the loyalist scum Eagle Warriors piling out in an ordered fashion, but Erex and Barbas were bounding towards the Drop Pod as it landed. Erex's longer and stronger legs carrying him ahead of his Executor, his feet taking on the form of cloven hooves. The squad's plasma gunner was the most prominent threat so Erex leapt the last dozen metres before crashing into the Imperial Astartes, his hooves breaking the Marines chest and abdomen as he swung his crozius at a second Marine, caving in its head. His claws were wreathed in warp flame and he gripped the head of a third and the marines armour began to melt under the heat before Erex savagely tore its head off, spinal cord following in an explosion of molten gore. He crozius swung at the knees of another Astartes and the warrior fell to the ground and Erex tore open his chest with a single swipe of his claws. A plasma bolt struck his right arm, most of the energy dissipating on the warp field he constantly projected but it still burned his daemon flesh arm. His return swing was blocked by a chainsword and the sergeant kneed his groin before smashing his sword hilt into Erex's face, breaking teeth and causing him to spit the black ichor that was his blood. Erex's claw was knocked aside before his opponent's sword bit into his arm, ichor, flesh and armour clogging the teeth of the blade. His free hand found a purchase around the sergeant's gorget and he was lifted into the air. Snarling savagely Erex drove the scum into an embankment. Driving his daemon arm into the Eagle Warriors chest plate, shattering the golden Aquila. Erex spat another globule of ichor before his claws punched up into the sergeant, tips emerging through his back. Curling his finger his broke the Marines spine and ripped it out, his foe collapsing in a spineless heap. The coincidence wasn't lost on Erex, before he pulled himself back t knowing that this was all part of Tzeentch's plan for the galaxy. The sound of snapping bones and shattering ceramite caused Erex to spin around where he saw his Executor writhing on the ground, surrounded by the broken bodies of the rest of the eagle Warrior squad. He body broke apart, his face taking on a porcine aspect, crowned by iridescent feathers, an additional pair of gangly limbs burst from his torso and vestigial wings grew from his back, and lastly a scorpion like tail emerged dripping with a virulent poison. The spawn reared and roared in pain before sniffing the air and ran off, screeching with an unrestrained fury. Erex picked up the Executor's blade, forged from the stuff of nightmares itself. The blade was linked to their ship, the Herald of Mutation, and was needed to perform the sacrifices that would appease the vast ships daemonic spirit and allow them warp travel. Breaking the walls between realities and allowing the ship to step fully in the warp, its daemonic nature letting it have a foothold in both realms at the same time, permitting the will of its master Selunax allowed it of course. A slight tug at his spirit let him know that the former Executor was felled finally. By a skull helmed warrior in black, the same position Erex held in his former life, before he stood as the right hand of Sorcerer-Prince Selunax, and the guidance of all the Disciples. This one must die.

His voiced boomed from his tortured mouth,' Come and die servant of the Corpse Emperor!'

'I will scour your trace from His galaxy Daemon!' came the reply.

Erex expected nothing less and both bringers of their respective faiths charged into battle. A battle of wills began as well as that of physical combat. The two Chaplains, one dark, one light struggled in a brutal combat that seemed to eclipse all others. Erex's crozius arm was knocked aside but he spewed forth flame, which was turned aside by the chaplains Rosarius. His demon arm punched again and again, but the well crafted armour held firm, with only minor crack emerging in the battle plate. In response the chaplain fired his bolt pistol at point blank range, tearing holes in Erex's armour. Erex head butted the chaplain, causing the brief time needed for him to bring his crozius down on the chaplains head, but it was stopped mere centimetres from the helmet. Erex pushed all his might behind the blow but the muttering of the chaplain held the field in place. Thus distracting his opponent, Erex's clawed hand closed around the Executor's Blade, the material it was forged from cared not for the arcane protections of the Rosarius. Erex stabbed up again and again. He let blade hang by his side as he pulled out the chaplain's primary heart, crushing the chaplain head with his crozius. Taking a bite from the still beating heart he felt the wall between worlds grow thin, and a warp rift burst into existence above Sorcerer-Prince Selunax and a horde of daemons charged onto the battlefield, condemning those survivors to eternal damnation.
