Geratomran Reconquest - The Battle for Magor's Seat: As the Imperial tacticians had foreseen, the Chaos Warfleet retreated once the great Ark Mechanicus delivered its precious cargo. The naval duel had cost both fleets dearly. One vessel had been downed, crashing with earth-shattering force onto Geratomro's surface and plunging the planet's entire southern hemisphere into darkness, the sun's rays occluded by thick black clouds of pulverised earth and rock. The air itself tasted of metal and dirt and some troopers began to wear their Rebreathers at all times as a precaution.Under the cover of night, the super-heavy tanks of the new composite unit designated "Ultra" left the Imperial encampment well before dawn. Thick, black rain had begun to fall, an unclean mix of ash, earth and atomised human bodies. Visibility fell to a few hundred yards, requiring the four tanks of Ultra to navigate solely by Augur, all of their lights dimmed so as not to give away their position.Progress was slow, for the landscape before them had become a broken, war-blasted wasteland. These were the once fertile plains designated Magor's Fields. Whatever beauty the land possessed had been torn away, transformed into a lunar landscape of craters by orbital bombardments and conventional artillery strikes.Ultra was comprised of only four tanks under the nominal command of Honoured Captain Lo Parrigar, commander of the "Lucky Eights." His was the only Stormlord in the formation and the other three were Titan-killing Shadowswords. Of these, two were drawn from the Atraxian 18th Super Heavy Company and called Indominus and World Burner. Their simple grey livery easily distinguished them from Lux Imperator which bore the standard tan-and-green camouflage pattern favoured for fighting on temperate worlds such as Geratomro. While Parrigar's Stormlord -- the Righteous Vengeance -- led the way, the unit was led by Lieutenant Askelios in World Burner, the most experienced Shadowsword commander in the entire army.The four super-heavies of Ultra were not entirely alone, for several Atlas Recovery Tanks accompanied them, their powerful engines and large Dozer Blades needed to transform their chosen hiding spot into a defensive position. As the group progressed further on the edge of the wasteland, it encountered a very large crater -- large enough for the three Shadowswords to lie within and maintain a good line of fire on the outlying district of Magor's Seat, making it the perfect spot to lay their ambush.As soon as the three Shadowswords had secured themselves, the Atlases began their work. The Stormlord's complement of embarked infantry, led by Bannick's cousin, began digging a simple line of trenches to defend their position from enemy infantry. Wishing to escape the scrutiny of their attached Commissar, a vulture of a man answering to the name Chensormen, several of Lux Imperator’s crew chose to step outside into the rain rather than help their comrades dig trenches.The work was completed some ten solar minutes before the scheduled beginning of the assault. The 18th's support vehicles withdrew, leaving Ultra alone. Hidden behind their earthworks, the three Shadowswords lay in wait, their capacitors empty and reactors turned down to minimum. While this would blind them to enemy Augurs, this also left the Shadowswords vulnerable, for they would be unable to fire or move without giving away their position.Around them, Jonas' infantry platoon occupied the freshly-dug trenches, while Righteous Vengeance acted as a mobile reserve and watched the formation's vulnerable rear. Anticipating an encounter with enemy Chaos Space Marines, Lieutenant Jonas Vor Anselm Lo Bannick had ordered his weapon specialists to form a Special Weapons Squad, their Meltaguns and Plasma Guns capable of cracking open the enemy's Power Armour. All that remained to do was to wait.As the agreed hour for the start of the assault arrived, a huge column of troops and engines of war left the Imperial encampment, the advance sheltered from enemy interference by the continued bombardment of the Imperial Navy. At the head of the column advanced the Titans of the Legio Crucis. The Warhound-class Titan War's Gift opened the way, zigzaging to the left and right of the advance, scouting the way for its heavier counterpart, the Reaver-class Titan Ultimate Sanction, Princeps Yolandesh's engine. They were to be the bait to draw out the enemy Titans out in the open.Further to the west, the main Imperial army followed what remained of Highway 4. At its head a big concentration of tanks of various types led the way, with composite unit Epsilon roughly in the middle of the armoured column. Led by Honoured Captain Lo Hannick and his Hellhammer Ostrakhan's Rebirth, two Baneblades -- Artemen Ultrus and Fidelus -- two Stormlords of the 8th Paragonian Super Heavy Tank Company and a single Stormsword, the Refutation of Sin, advanced in tight formation. Behind them followed the APCs and finally the marching columns of the infantry.With the highway having been reduced to much the same state as Magor's Fields, the advance proved slow. While unit Ultra kept to strict Vox-silence, the marching army followed no such restraints and flooded the communication channels with status updates, call signs and orders. But the enemy soon showed his hand.
