Broken, The - Mystery Deepens: As both Inquisitor Drake and Magos Fane argued over the expedition's fate, Sergeant Starn, once feared lost, found his way back the Fury's surface. In the palm of his Power Fist he held a curious object he had discovered deep in the bowels of the space hulk -- a Mark V Heresy Pattern Power Armour helmet of the Adeptus Astartes.The helmet was truly ancient, its original livery long erased by the passage of time, but its discovery could mean only one thing: that Space Marines had been -- and maybe still were -- on the Fury. Yet again Inquisitor Drake's techno-savants proved invaluable, as the helmet's production stamp and number allowed them to trace the helmet back to its original owner.With no means to determine if these mysterious Astartes were the remnants of some faithful Chapter's lost detachment, or the harbinger of something far more sinister, Marneus Calgar formally took command of the mission. His first orders were for the full mobilisation of the 5th and 7th Companies and the awakening of their Dreadnoughts. The Astartes cyborgs' brute strength would be sorely needed to clear the Fury's surface and establish a forward base of operations on the space hulk.Led by Sergeant Starn, an expedition composed of the Ultramarines, the servants of the Mechanicus and the Inquisition would venture deeper into the labyrinthine corridors of the space hulk and pierce its mystery.Marneus Calgar decreed that he would lead 5th Company's men and their Captain whilst Captain Ixion and his 7th Company would remain on the surface of the hulk and secure the base. Tigurius would stay on the Octavius and command the fleet while using its powers to forewarn them if the Fury was about to disappear into the Warp again.As the Imperials cleared the upper levels of the hulk and made their way deeper into the Fury, installing vox-relays every few Terran miles within the massive vessel's interior to maintain communication with their fleet, Marneus Calgar could not shake a sense of grim foreboding. Darkness was surrounding them, the space hulk's metallic dust clouds and radiation levels playing havoc with their Auspexes and even the targeting systems of the Space Marines' Power Armour.Cut off from quick reinforcements, navigating the dark corridors only by sight, and relying on their built-in illuminators to shed light on the path ahead, left the party extremely vulnerable. Both Inquisitor Drake and Calgar understood that the further they travelled within the hulk, the harder it would be to withdraw. They feared that an enemy might be monitoring their progress and would strike once they had been lured deep enough that easy retreat was no longer possible.At the same time, the further the Imperial party ventured into the vessel, the more signs of deliberate alterations of the hulk became apparent. The interior of the space hulk was clearly inhabited, and even the oxygen levels in the interior's atmosphere approached breathable levels. The Imperials were clearly not alone.As they ventured deeper into the hulk, Magos Fane requested that he be allowed to lead a detachment of his Mechanicus personnel to investigate a chamber from which his superior Augurs had detected the power output of several systems that were still operational inside the hulk. With the Chapter Master's permission, Fane left the main body of the Imperial column.While his adepts began to work on several cogitators still drawing power, an urgent transmission for Inquisitor Drake was relayed by the Octavius. Consultation of the Inquisitorial archives had yielded its reward.Drake's archivists had informed him that the mysterious Space Marine helmet Starn had found within the space hulk was nearly three Terran millennia old and belonged to the Viridian Consuls Chapter. That Chapter of the Adeptus Astartes had been declared lost in the Warp in the wake of the infamous Abyssal Crusade. As a gesture of trust between them, Drake shared this information with Calgar, who promptly asked Tigurius to gather further intelligence on the matter.Magos Fane then presented the results of his own inquiry. Fane and his Adepts had recovered a digital map that laid out the system of tunnels that comprised the upper levels of the Fury. These tunnels were extensive and had been carved out through the bulk of the massive voidship over the course of several Terran centuries. Magos Fane intended to study the rest of the data and the neighboring compartments of the hulk, but Calgar refused.He ordered the Magos to copy the map and rejoin the main Imperial column, denying him additional time in the Cogitator chamber. Frustrated by this decision to short-circuit his exploration, yet unwilling to openly disobey the Chapter Master, Fane programmed his best Artisan, Alt-seven, to return to the chamber and investigate the rest of the data and especially the hidden chamber they had discovered behind the Cogitator stations when an opportune occasion arose.
