There is a glimmer. A flash. Beams of coherent energy, beams of staggering magnitude, rip from Calth and from its orbital stations.
Calth has a weapons grid capable of keeping at bay an entire expedition fleet or primary battlegroup. Only the most devious and ingenious treachery has circumvented it today.
The weapons grid begins to discharge. Calth begins to kill the neighbouring planets in the Veridian system.
It starts with a massive asteroid world that orbits the system beyond the circuit of Calth’s moons. The asteroid, called Alamasta, is the main remnant of a planet that once occupied that orbital slot. It is now a rock the size of a major satellite.
It is no longer called Alamasta. It is known as Veridia Forge. It is the system’s principal Mechanicum station, and the most significant manufacturing venue in six systems.
Veridia Forge is helpless, its systems crashed by the same scrapcode that brought the Calth grid down.
It has no shields, no responsive weaponry, and no means of evasion.
It takes four prolonged strikes from the weapons grid. The first two burn away surface rock and immolate rockcrete bastions or adamantine bulwarks. The third voids the main fabricatory to space, and combusts the forge world’s reactor power systems.
The fourth causes Veridia Forge to explode like a newborn star.
For the next eighteen minutes, Calth has no nightside.

Ventanus throws the speeder into reverse thrust. The auspex is smashed and useless. He only saw the gun-carriage when he cleared the corner.
The speeder reverses down the slipway with a violence that lurches Ventanus and Selaton forward in their seats. Cannonfire is already chasing them. Rapid fire from the grav-compensated carriage, a quad-weapon monster, shreds the barns and storeblocks around them. Cargofabs and payload warehouses explode or disintegrate. Rockcrete walls shiver and exhale dust as shots pummel through them. Window ports burst out.
‘Not that way either,’ says Ventanus.
‘Agreed,’ says Selaton. He’s got the autocannon across his knees, and he’s checking the munitions feed. There’s not much left in the hopper.
Ventanus swings left, and they race down a dank rockcrete underpass, zip between two huge aerospace manufactories, and skirt the perimeter of a burning excise facility. There are bodies everywhere. Civilians, Army, and far too many Ultramarines for Ventanus to be even slightly sanguine about. Men are dead with their weapons still sheathed or covered. Men cut down without the opportunity to face their deaths.
Heaps of cobalt-blue armour – limp corpses inside scuffed plate – line the roadways and arterials. Some have been stacked against fences and walls like firewood. Some have been cut open and emptied. A few have been nailed to posts, or against the sheet-metal sides of buildings.
Some appear to have been butchered or… eaten.
Ventanus doesn’t understand this. He presumes they are victims of some explosive weapon type new to the arsenal of the XVII. Theoretical. That’s the best case theoretical. Ventanus hopes it turns out to be the practical too. The theoretical alternatives are too indecent to consider. The Word Bearers are allied with some species of carnivorous xenoform. The Word Bearers are indulging in some ritual cannibalism…
Ventanus doesn’t need much more of a reason to make war to the death against the Word Bearers. The injury they have done to Calth and to the XIII, that is cause enough. Their treachery, that is cause enough. Their relentless, merciless prosecution of attack, beyond any measure of honour, that is enough.
But this desecration, this takes his casus belli to a whole new level. This is not a just war, this is a war crime. It defies and shames the codes and precepts of the Legiones Astartes, codes and precepts set down by the primogenitor Emperor. The Word Bearers have perverted any semblance of the true and legal path of the Imperium, or the moral code of mankind.
Here and there, Ventanus spots signs that have been daubed on walls, presumably in blood. Eight-pointed stars and other devices he is not familiar with, and the sight of which make him uncomfortable.
Over the chug of the speeder’s engine – a chug that is developing a worrying, clattering under-note – Ventanus can hear the rattle of other gun-carriages moving through the nearby streets. They are in the industrial hinterland between the starport proper and the city. Ventanus is desperate to find a route that they can use to break out and head north-west to Erud. His primary concern is re-establishing contact with his company and the other units in the Erud muster. If they’ve come through this intact, or approximately intact, he intends to make them the spearhead of a counter-strike.
A haze washes across the city and the port. It’s smoke, in vast quantities, but it’s also vapour. Steam. A fog swathes the skyline, blanketing the river basin and turning millions of individual fires into soft orange smudges. Ventanus has seen that phenomenon before, when large bodies of water have been flash-evaporated by sustained energy discharge. A dead ocean condenses over the city lowlands.
They turn another corner, and see six Word Bearers advancing down the freight lane ahead of them. The Word Bearers challenge them, and then open fire.
The speeder rocks under the hits as it starts to reverse. Its armour is pretty solid, but Ventanus knows it’s taken quite enough punishment. He glides backwards, hoping to swing-turn on the hardpan in front of a fabricator shed and find another path. More Word Bearers open up on them, firing from an overwalk, and from a girder bridge between two manufactories. A mass-reactive round explodes against the side of the cab, where the roof is already peeled back and torn. The shock lurches Selaton hard.
They’re running out of ways to turn.
Ventanus reverses faster. He runs down two Word Bearers who emerge behind them. Their crimson-armoured forms are slung out from the repulsors at the speeder’s plated back end and fall, bouncing and clattering across the rockcrete.
But he can’t simply run down the gun-carriage that’s rolling out, facing their back end. It’s twice their size, twice their mass, and it starts traversing its quad-guns to target them.
‘Go!’ Selaton shouts. ‘Go! Through them!’
Ventanus kicks the speeder forward again, cranking thrust. He knocks down one of the Word Bearers they have already smashed aside once. The brute was regaining his footing. The right front wing catches him hard, folds him around the reinforced fender, and tosses him sidelong. He tumbles, and lands in a way that speaks of a severed spinal cord.
Selaton rises in his seat, bracing the autocannon against the sill of the screen. They’re heading directly for the Word Bearers squad that cut them off in the freight lane. They’re also running right through the hail of fire chopping down from the overwalk and girder bridge. Shells slam into the ground around them, pluming fire and grit. Others thump the bodywork like piledrivers.
Selaton kicks off with the cannon. He gets a good angle, given the improvised circumstances, and stitches a line of shots along the girder bridge, ripping handrail spars and shredding the metal balustrade. He knocks two of the enemy shooters off their feet, and then licks across a third. Ventanus sees a helmet explode like a red paint flare. The casualty rocks backwards off the bridge and hits the ground a second after they’ve passed underneath.
Selaton drops his angle and guns down one of the ground troops. The rotating cannon chews the figure up, shredding him like a sack of meat and metal chaff. The others stand their ground, firing straight at them. Ventanus, his grip unflinching, sees a mass-reactive round pass through the cabin between his head and Selaton’s and exit through the back port-slot.
