While defending the world of Hydra Cordatus from the Iron Warriors, the Imperial Fists 3rd Company is slain to a man. Determined to rebuild his old company, Captain Tor Garadon receives permission to leave the 2nd Company to work with the 3rd. While Garadon and a unit of veterans work to rebuild the company at the Phalanx, Lysander and Vorn Hagan take five companies of the Chapter to worlds near the Eye of Terror in a Crusade against Chaos.
However the 3rd Company does not remain idle for long. In 999.M41 Warsmith Shon'tu, having survived the Fall of Malodrax, returns to exact vengeance against the Imperial Fists. Looking to upstage Abaddon the Despoiler's 13th Black Crusade, Shon'tu allies with the Daemon Be'lakor and plans to launch an attack on Holy Terra itself by hijacking the Phalanx's enormous firepower to unleash a bombardment on the Imperial Palace. Shon'tu and Be'lakor's forces succeed in boarding the Phalanx in a surprise assault. Under Garadon's direction the newly formed 3rd Company fights with determination that belies their inexperience, fighting off attacks by Daemonic hordes. Ultimately, Garadon delays the incursion long enough for Phalanx to rouse its engines and enter the Warp, thus ending the immediate threat to Terra. With the ship hurtling across the Immaterium, neither side is able to contact their allies. As the Imperial Fists make their last stand, the Legion of the Damned materialize out of fire and join the battle. Though the Legion prevented total Chaos victory, the battles outcome was still far from certain.
Be'lakor was eventually able to summon a Warp Rift inside the Phalanx itself as part of a goal to capture the vessel. The few remaining Imperial Fists defenders were by this point massively outnumbered by the traitors and slowly losing control of the vessel to Iron Warriors machine-curses. In desperation, Garadon used the guns of the Phalanx to blast off the "infected" parts of the station, losing 10% of its total mass in the process. Ultimately however the Imperial defenders seemed doomed by a final Chaos assault until the Legion of the Damned arrived to save the Imperial fists, defeating Be'lakor. Afterwards, the Imperial Fists and Legion forces decided to move to Cadia to aid the Imperial defenders in the 13th Black Crusade.
