War of the Beast - Second Battle of Ullanor: Despite this setback, Lord Commander Koorland remained undeterred, realising that in order to defeat The Beast and his WAAAGH!, they needed to counter the greenskins' potent psykers. Once again, Inquisitorial Representative Veritus displayed his uncanny knowledge of the past, when he informed Koorland of the existence of the last bastion of the Sisters of Silence upon the world of Nadiries. He told the Lord Commander that he had long sought them out even before the events of the War of the Beast. Following Veritus' lead to the world of Nadriries, located in the far reaches of the Segmentum Pacificus. It was here, that the last forgotten bastion of the Silent Sisterhood had remained for 1,500 years. When Lord Commander of the Imperium Koorland arrived, he found Nadiries under siege by the Orks, who feared the Pariah psyker-killers. Koorland led the effort to lift the siege, and once inside, he attempted to convince the reluctant Sisters to join him in his Crusade.The leader of the Sisters explained that they had been cast out by a distrustful Imperium, and although they were fiercely loyal to the Emperor and the Primarchs, they would rather see the now-corrupt Imperium burn, rather than aid it in its time of need. Koorland convinced the reluctant Sisters to join him only after he revealed that he had the blessing of the Primarch Vulkan himself. Devising a new plan to defeat The Beast, the Deathwatch captured several Ork psykers on Eidolica, Plaeos and Valhalla. Koorland intended to use the null effect of the anti-psyker Sisters of Silence to create a reverse-WAAAAGH! effect through the Ork psyche, and essentially decimate the greenskin hordes of The Beast using their own power against them. After successfully conducting their theory against a large Ork force on the world of Incus Maximal, the Lord Commander declared his intent to launch a second invasion of Ullanor Prime. This time they would slay The Beast utilising their new secret weapon.Leading a large, but much smaller, Imperial Crusade during the Second Battle of Ullanor, this force was comprised of several battered Chapters, including: the Aurora Chapter, Black Templars, Blood Angels, Brazen Claws, Excoriators, Fists Exemplar, Iron Knights, Iron Snakes, Raven Guard, Storm Lords and Space Wolves. This strike force was further augmented by the Deathwatch, several Astra Militarum regiments consisting mainly of several veteran units of the first campaign, Frateris Templar, Skitarii, several cohorts of Legio Cybernetica, Imperial Knights, several dozen Sisters of Silence, Inquisitorial Storm Troopers and the remaining Titans of the Legio Ultima. Due to the losses sustained by the Imperial Navy, the Imperial Crusade was transported by the Inquisition's Black Ships provided by the co-Inquisitorial Representative Weinand, who became the co-commander, alongside the Fists Exemplar's Chapter Master Maximus Thane, of the invasion phase of Ullanor. The Lord Commander would personally lead an assassination force to seek out and slay The Beast, consisting of the following: Black Templars High Marshal Bohemond, Deathwatch Chapter Master Asger Warfist, a single 6-man Deathwatch Kill-Team led by Raven Guard Sergeant Tyris, the Imperial Assassin Esad Wire, the Skitarii Ranger Alpha 13-Jzzal, a squad of 6 Sisters of Silence led by Knight Abyssal Kavalanera Brassanas, Commissar Heliad Goss and two Ogryns.The Imperials began the second invasion by launching several damaged warships manned by skeleton crews, sacrificing themselves spectacularly as they collided with the large energy field that protected the world's capital of Gorkogrod, causing it to overload. With the shield temporarily disable, Koorland's assassination team used this opportunity to teleport into Gorkogrod's central complex. The Imperial strike force met little resistance, and quickly realised that The Beast was already aware of their presence. The energy shield was quickly reactivated and a large Ork force was diverted towards the Imperial strike force in the palace. Meanwhile, a large Ork fleet suddenly appeared in orbit and launched an ambush against the Imperial fleet. Though the trap was set by The Beast, Koorland would not be deterred, as he was intent on succeeding, where Vulkan had failed.The Imperial strike force fought a desperate battle of survival, but eventually, they managed to reach the complex's central throneworld, where they encountered six thrones, six statues and six banners. Seated in one of these thrones was a massive Ork armoured in mega armour. The creature was as large as a walker. To compound matters, the Imperials were surrounded by a large force of Gargants that stood taller than an Imperial Reaver-class Titan. As the other members of the strike team held off The Beast's honour guard, the Lord Commander and the other Space Marines engaged The Beast. Though they proved ineffective against the massive creature, they held off The Beast long enough for the Sisters of Silence to enact their ritual and activate their anti-psyker effect. Due to the Sisters of Silence's Pariah effect, the Ork Psyker that was present imploded, which resulted in a sort-of feedback effect, causing a reverse-WAAAGH! chain reaction that swept across Ullanor, affecting the massive horde of greenskins. Temporarily disabling both The Beast's honour guard and several Ork vehicles, the Warboss was only momentarily disabled, which allowed for one last desperate, final attack by Koorland and the assassination team, which narrowly slew the fell creature.Though Koorland's plan succeeded, the Imperials' victory was short-lived, as a larger and even more vicious Ork appeared. The Lord Commander recognised the creature as the original Beast that had fought the Primarch Vulkan during the first invasion. It was revealed that the creature Koorland killed, was in fact, one of six "Prime-Orks", each a veritable Beast in its own right. After this revelation, the newly revealed Beast swept aside the Imperial assassination force and Koorland was soon slain by The Beast, crushing the Lord Commander under one of its massive boots. With the death of the "Last Son of Dorn", the Imperials recovered the fallen Lord Commander's body and fled the surface of the planet.
