Siege of Vraks - Guardian of the Portal: It seemed likely that Zhufor and his men had used the portal to escape throwing themselves to the whims of their gods. They would emerge wherever Khorne deemed it fitting, perhaps recalled to some daemon-world deep in the Eye of Terror, perhaps cast to some other bitter warzone to again fight for their master The Traitor Legionnaires had not left without leaving their enemies a final foe The daemonancers had summoned and bound a creature to protect the portal It was Uraka Warfiend, a Daemon prince of Khorne. His legions now awaited within the inner keep, a daemonic force sent as sentries to guard the portal for all eternity.They did not have so long to wait. On 411.830.M41 the forces of the Ordo Malleus and their Grey Knight squads teleported from the Honours-Amentum into the Aedificium to clear the last stronghold of the enemy and destroy the warp portal on Vraks forever. Preceded by the orbital bombardment of melta torpedoes and barrage bombs which further pounded the rubble and ruins, the teleport chambers hummed with barely contained power before sparking into life with a crackle of lightning, casting the Inquisitors and the Grey Knights squads through the Warp to reappear seconds later within the inner keep.Instantly they were beset by the Daemon s legions awaiting them. As if from nowhere the Bloodletters, Flesh Hounds and Juggernauts appeared, screaming their god s name as they charged recklessly into me righteous fury of the Grey Knights’ bolt gun and psycannon fire, which send them shrieking back into the abyss. Lord Hector Rex was again in the midst of the fighting. Arias scything through the blood-red ranks of the foes, his eyes turned into pits of white fire as psychic energy flowed through his mind, the aura of his power enough to drive the daemons before him.With nemesis force weapon, psycannon and incinerator, the Grey Knights scoured the Aedificium. Brother Captain Stem led them, his own sword ablaze with psychic flames that destroyed the daemons upon touch. He hacked and cut, parried and hacked again alongside his brothers, chanting prayers for the exorcism of the hated denizens of the Warp.Then Uraka Warfiend himself came to meet the Grey Knights hero. A massive beast snarling and spitting, fangs encrusted with the Wood of his past victims. Encased in the warp-forged brass armour of Khorne, in his hands he held a massive pole-axe, a cruel executioners weapon. With it, he bellowed he would take Captain Stem’s head and Khorne would mount it as a trophy upon the wall of his throne room, and throw his body to the Fleshhounds to feast upon.Stem’s indomitable will could not be broken by mere boastful words. Uraka might be a champion of Khome, but Stern was the instrument of the Emperor’s justice imbued with the divine wrath of Mankind’s true god - and that wrath he unleashed. Power surged through him, a blazing bolt leapt from his brow and smashed into Uraka, who reeled wounded, then charged. With his great axe swinging in a figure of eight about his head he smashed it down. Stern dodged aside, his bulky aegis suit not impeding his agility as he raised his force sword again, thrusting it upwards seeking a weakness in the red beast s armour. His blade turned. Stern felt the unholy strength of Uraka as he spun, the tong spike in his pole axe’s butt diving into the ceramite plating and drawing blood from Captain Stern. Wounded, Stem staggered away, his vital signs fluctuating wildly, his suits bio-systems damaged. Uraka strode after his foe, the long axe drawn back, ready to strike again, eager for the kill. He swung, and Stem parried, blocking the axe, but the strength of the beast sent him crashing to the floor, his sword smashed aside.Justicar Ophia arrived, his squad with him, and saw his commander down and wounded. The guardian of the portal was stood over Stem, bringing his axe back for the kilting blow. Instantly, Ophia fired, as did his men, a volley of psychically charged bolter rounds detonated around the Daemon prince, tearing chunks from his armour. Wounded and enraged Uraka saw his new foes and lurched towards them. He saw Captain Stem too late, his sword recovered lunging after him. The white-hot Wade of his force weapon found a fresh niche in the brass armour and Stem drove it home with all his might. Uraka bellowed his last. A roar of pain and anger that boomed around the keep. Then, in a flash he was gone - banished back to his master’s dark realm.That powerful thrust was the Grey Knights Captain’s last action of the campaign. Still bleeding, he was returned to the strike cruiser for urgent medical attention whilst Hector Rex and his men dispatched the last of the guardians. With the daemons destroyed, they gathered before the rune engraved columns that encircled the sealed portal and combined the power of their psychic minds into a twisting holocaust of destruction that vaporized the portal. It was over.
