Gorehead, a raging little beast, had fired in support of its keening brethren, trying to stifle the gunline’s output and disrupt any aim at the Necrostar. A cloud of small craft had formed forward of the Imperial line, a massive dogfight swirl like pollen spilling from a flower head. Fury flights, along with heavier support squadrons loosed by the Imperial ships, had ripped into the formations of Archenemy killships. One especially sustained duel was being fought to keep the daemon interceptors away from the Aquila bearing the lord militant.
Gorehead’s primary weapons scored a decent hit against an Imperial destroyer called Phalanxor, enough to impair its void shields, and rendered it ineffective for long enough to allow Necrostar Antiversal its passage. Necrostar Antiversal was spitting massive hullcutter missiles at the Imperial flagship, and its primary energy batteries were cycling up to strike.
Sepiterna, an almost stationary island more than ten kilometres long, reached out to deny the obdurate intruder. Beam weapons, red sparks in the brown twilight of the void, found and neutralised the running missiles, igniting quick bright flashes of white fire. Then the principal weapon fired, and slapped the charging Archenemy vessel sideways. Necrostar Antiversal spun away, all stability control lost. Its port bow section glowed with a fierce internal blaze, and atomised structural debris squirted from its lurching bulk. It stopped screaming its name and instead simply screamed. Demented with damage and pain, the Necrostar Antiversal fell away, righted itself, and then began to flee. The flight may have been caused by a drive malfunction or a loss of helm. It was frantic and headlong. The Necrostar’s realspace engines went to full burn, one of them clearly misfiring and crippled to such an extent the ship was leaving a dirty trail of burning fuel and radioactive blowback behind it. It veered away like a comet, and streaked towards the distant limits of the system like a scolded hound, beaten and driven away yelping.
Shipmaster Spika was aware that his artificers were desperate to lower shields. Sustaining them at maximum was depleting the reserves at a nightmarish rate. With fifty per cent of the enemy strength dismissed, surely the fight was done. Any grasp of tactical logic could tell you that.
Spika knew from bitter experience that when it came to void fighting with the Ruinous Powers, tactical logic had little or no place. He had, for many years as a more junior officer, studied the behavioural habits of large carnivores, particularly in such circumstances as hunting, protecting a kill or defending their family group or their young, as well as their actions when wounded or cornered. That, he had found, was most often how Archenemy ships performed. They did not make calculated strategic moves as though the battlesphere was a giant, three-dimensional regicide board. They did not observe the traditions and crafts of Battlefleet tactics as learned and studied by the officers of the Imperial Navy.
They fought like animals in traps, like wounded rogue beasts cornered in a canyon, like predators in the forest gloom. They ignored logic, or technical comparatives, or the output of threat assessment cogitators.
That, in the considered opinion of Clemensew Spika, an opinion not shared by the Departmento Tacticae of the Imperial Fleet, an opinion that had probably hindered the progress of his career over the years, that was why the Archenemy often won.
Tormaggedon Monstrum Rex, the behemoth capital ship of the enemy force, turned towards them. It had lost its appetite for a direct fight with the mighty Sepiterna and its resolved gunline, but it was evidently quite prepared to make a parthian shot or two at the Armaduke and the Libertus, pushed forwards and vulnerable as they were.
Spika ordered a hard evasive turn back towards the sun, and watched on the strategium display to see that Libertus was doing the same. If they could at least place themselves decently in the optimum reach of the main gunline, it might be enough to dissuade the monster from harrying them.
But the Rex was fast. It was the single biggest vessel involved in the fleet action; not as stately and deep through the waist as the majestic Sepiterna, but longer and of significantly greater tonnage. It accelerated, however, like a frigate. A light frigate. It was quite the nimblest supermassive Spika had seen since the Palodron Campaign against the diseased craftworld. Its internal glow, coal red, flared as if bellows had been applied. It powered in, weapon banks developing charge for a shot.
The Sepiterna spurred its whole gunline forwards, but it was a gesture that would have little practical effect in the timeframe. The Aggressor Libertus, a significant ship in its own right, began firing as it turned, loosing as much as it could at the oncoming monster. The daemon ship’s shields held firm. The Libertus’s barrage, enough to strip a hive down to the mantle, spattered off the voidshields like firecrackers.
The Rex fired. The energy whiplash, so bright it was not any sort of colour at all, struck the Libertus in the small of the back, popped its shields like a soap bubble, shattered the hull jacket, and cored a hole down through the decks like someone cracking through decorative icing to slice open a layer cake. It was not one blast, one flash. The jerking, kinking coil of energy linked the two ships together like an electrical arc for almost twenty seconds. Its point of impact was brighter than a spot-welding torch. The burning force sheared through the Libertus, cutting it in a line that ran along its spine towards its prow. The cruiser was almost bisected lengthways. When the awful weapon finally shut off, the Libertus broke up, not cleanly in half like a nutshell, but into two large sections along a surgically straight line. Almost a third of the cruiser’s tonnage sheared away along the port side from central environmental to the prow, armour splintering like glass, internal contents, crew and debris voiding in a cloud like smoke. The sectioning was so precise that Spika could see the cross-cut through the decks through his viewer, like a cross-section display in one of the glass cases at the Admiralty. He saw fires burning inside, pressure compartments blowing, bulkheads shredding, atmosphere venting, hydraulics and other fluids billowing out in quicksilver blobs. He saw slicks of debris litter and realised they were masses of weightless corpses.
A secondary blast blew out the Libertus’s ruptured plasma drives, sending the larger of the two hull portions spinning nose over tail out of a bright yellow explosion. The spinning section clipped the other hull portion and sent it tumbling out to one side, regurgitating material into the void.
The Rex brushed past its kill and closed on the Armaduke, dwarfing it. It was set to send the Imperial battlegroup home with at least three dead.
Its main weapons gathered charge, cracking fury in the reservoirs beneath the skin of the hull. It closed tighter still, perhaps intending to riddle the Armaduke to scrap with its small batteries rather than waste the main charge.
Spika felt its shadow on them. It overhauled them, blotting out the sun, a leviathan ten or twelve times their size. Every sensor on the Armaduke’s bridge screamed. Every alarm sounded. Spika instructed his gun crews to unload everything they had.
