To reclaim that which is lost and avenge those who's lives have been taken.

Imperial Battlefleet Peregrinus drifted through the Immaterium. The powerful Warp drives churned, projecting the ships through the Abyss. A scholar that Lord-Inquisitor Jonas Peregrinus had once read some of the works of had said something, many thousands of years before Warp travel was a possibility for humanity, was extremely fitting for the relationship between man and the hell that attempted to find holes in the Geller Fields that kept those inside of the ships safe.
"When you gaze long into an abyss the abyss also gazes into you."
Quite fitting for the realm that writhed outside of their safe shells of ships. Few could look into the tumbling waves of insanity that made up most of the dreamscape of the Warp without being looked back, and many of those whom looked into it would go insane. Not the Lord-Inquisitor. A Psyker of Beta-level, his faith kept him safe. And his faith had caused him to take an oath against a foul xeno, an enemy of the God-Emperor who dared to defile one of His holy relics. A Nemesis daemonhammer, stolen from a Chapter of Space Marines it had been gifted to, would not normally be something that an entire Battlefleet would be chasing. Perhaps one Inquisitor, maybe even a company of the Marines that had been offended. However, this was not the only reason to chase it. This Ork Warboss was one of a kind, a beast unlike any other seen in the history of the Ordo Xenos.
Weirdboss Zog-Ammer. Weirdboss.
Once a Weirdboy, an Ork psyker, who displayed unusually sophisticated skills for an Ork when it came to tactics, an Ork who could speak flawless Low Gothic, he was now one of the few Weirdbosses. Once captured by the Inquisition and tortured, he had taken it all in stride. Jonas had been presiding over the torture, and as the commanding Inquisitor at the time, he could have had the filth executed there and then, quickly. He could have snapped the Ork's mind with a flick of his wrist due to the lack of nearby Orks to boost his psychic power. But he had ordered an execution by beheading, to which the Ork replied by throwing a massive amount of stored psychic energy into a single attack, killing the Inquisitors and Interrogators presiding over the torture. The Ork had leveled half of the compound and found the weapon he had stolen, before escaping. Years later, he had found a Space Hulk, designated "Vengeance of the Traitor" or X197 by the Inquisition, and named it "Mork's Wraff." He had taken control of enough of it to use it to travel the galaxy, and he had not hesitated to attack the Imperium of Man. Returning to the world on which he had stolen the weapon, he fought both Imperial and Chaos forces. Completely annihilating the Chaos forces and almost completely killing the Imperials, he had turned away for pastures with more fighting. Enraged that he had been unable to catch the alien there, he took an Oath.
He would hunt this bastard down to the ends of the God-Emperor's domain and beyond. He would slay Zog-Ammer and reclaim the relic he had stolen.
This alone would not require such a large force. However, Zog-Ammer's Orks had grown even more powerful due to their participation in the War of Dakka against the Tau, and he was now headed for the Imperial system of Midghast. The Space Hulk he inhabited was unusually large, larger than almost any Imperial Naval Base. Headed for such a heavily populated system, he would slaughter billions of humans, take their resources, and rape the machinery of the system in his search for loot. In an attempt to intercept this, a truly massive force of Space Marines, Inquisitors, Guardsmen, Sisters of Battle, and other forces had joined together under the command of Lord-Inquisitor Jonas Peregrinus of the Ordo Xenos in an attempt to stop it, slay the Ork, reclaim the relic, and destroy the Hulk. Little did they know, there would be horrible things on that Hulk that none of them had expected...
Lord-Inquisitor Jonas Peregrinus stood on the bridge of his mighty warship, manipulating consoles. Sending requests for communication with others in the fleet, he pulled up those he would need to talk to. The General of the Vhermachtian Guardsmen, the Deathwatch Marine he had assigned as commander of the Marines in his general vicinity named Vertland, the Magos-Explorator, the Priest who would serve in joint command of the other guardsmen, Death Korps, with their Colonel commanding as well. Inquisitor Ibram Hess, commanding the Sisters of Battle - in particular, the Sisters of Silence - in joint-command with their Canoness. These were the forces that made up the core of the assault force, with the other forces acting for long-ranged support from their ships and for rearguard and flank protection.
"We will begin the assault in three hours. Magos, your ship will join in the landing assault. We will need bases of operations. The Retribution-class cruiser under your command shall remain at engagement range, using its Nova Cannon to cripple the capability of the Hulk to continue accelerating. We have identified what works as its propulsion system and have already sent the coordinates to you. General of the Vhermachtian, you shall join in the primary assault as well. Your guardsmen will form around my retinue and shall provide cover for us as we advance into the Hulk. We know not what horrors are in that monstrosity, so be on full alert. We will be striking directly for the heart of the Orks, we will extinguish the waste of life that Zog-Ammer is. Vertland, your Deathwatch Marines will act as part of an attack force with the Sisters, commanded by Inquisitor Hess, to attack from... this flank, where we have been able to determine a large concentration of Ork activity. By engaging them you will free up the path for the Vhermachtians and I. Mattius, you and the regiment of the Death Korps will insert yourselves after the Marines and Sisters have engaged the foul Greenskins, shortly after my force has begun its assault. Your objective will be to circle the Orks, cutting off all chances of their escape. All of their independent kroozers are located here -" he said, indicating a now lit section of the tactical map that was a model of the outside of the Hulk. "We will need to destroy these to cut off any chances of their escape." he said, and at that moment a new face joined the many faces in the conference. The Admiral in command of the fleet forces that would be bombarding and circling the Hulk to stop it from advancing too far into the system had joined in, and Jonas nodded.
"Admiral, you know your objectives. Surgical bombardments of their engines and kroozers, along with as many of their large-scale batteries as possible. When will we be within missile range?"
"Within two-point-four hours, Sir."
"Very well. Ready your troops, for we are going to begin the assault within three hours." he commanded, cancelling the conference. Proceeding to the troops ready-bay, the deployment bay, he began to run final checks on his troops. However, little did he know, there would be more than just Orks on that thing. And little did he know, the system itself would have a much larger role to play that anyone had previously expected...
