‘That won’t save him,’ Zhnev informed his Warsmith.

‘Chaplain, please. While there’s still time.’

‘Warsmith, I must press you for an explanation,’ Tauro Nicodemus said, after casting his eyes about the chamber. ‘I thought we were falling back to a further hold point.’

‘To what end, Ultramarine?’ Dantioch put to him as his gauntlets glided over the glyphs and runes of the console. ‘The Schadenhold is lost. Those loyalists remaining in the citadel will be overrun by Krendl’s reinforcements and the Omnia Victrumwill reduce the rest to rubble. This stronghold has bought the Emperor and Roboute Guilliman three hundred and sixty-six Ancient Terran days. Three hundred and sixty-six days bought with Olympian blood, so that they might formulate a response to the Heresy and better fortify the Imperial Palace – to buy a more favourable outcome than our own.’

‘What is the plan, my lord?’ Tarrasch said, his words giving shape to the thoughts of all in the chamber.

Dantioch looked about their cavernous surroundings.

‘This is the last of the Schadenhold’s secret strategies,’ the Warsmith said. ‘A final solution to any siege and an answer to any enemy that might push us this far.’

‘You said the fortress was lost,’ Nicodemus said.

‘There are many moments in a battle, when we can exploit our enemy’s weakness. We have, over the course of this siege, exploited nearly all of them. It is nothing less than irony that an enemy is at its very weakest mere moments before victory: when they are at their most stretched and committed in seeking such success. We are going to capitalise on that now.’

‘How?’ the champion pressed him.

‘In a siege, finalities must come first. We must accept our eventual doom and prepare for its coming. This chamber was one of the first I had constructed when crafting the Schadenhold. It is situated in the cavern ceiling, right in the rocky foundations of the fortress. It houses two important pieces of equipment, linked by a common console: a trigger for both if you will. The first is a small teleportarium with the associated generators required to power such a piece of equipment. The second is a detonator: wired to explosives situated at key weak points in the citadel foundations. Gravity will do the rest.’ Dantioch let the enormity of his plan sink in. ‘Chaplain Zhnev, please begin the rites for teleportation. Our journey will be swift but our destination important.’

As the Chaplain approached the transference tablets of the teleporter beyond, Tarrasch helped Ingoldt and Toledo get the barely breathing Vastopol sealed in plate.

‘Where is that destination?’ Nicodemus asked the Warmith. The Ultramarine was unused to being kept in tactical darkness.

‘The enemy has committed everything they have to taking this stronghold, undoubtedly leaving their own weak. We are going to teleport to the Benthosand take the bridge by surprise and by force. Brothers, time is upon us. Take your positions, please.’

As Tarrasch and the two Iron Warriors dragged the power armoured form of the Venerable Vastopol over to the transference tablets, Nicodemus hefted his storm shield up onto a shoulder mounting. The Ultramarine followed uncertainly.

With his helmet to the hatch, Baubistra said: ‘I think they’ve broken through, Warsmith. The enemy are approaching.’

‘Very good, Brother Baubistra: now join your brethren.’

As Baubistra strode by, Dantioch went through the motions of arming the explosives sunk deep in the ceiling rock of the Schadenhold’s foundations. Then he opened channels on all floors and vox-hailers across the citadel.

‘Idriss Krendl,’ Dantioch hissed. ‘Captain, this is your Warsmith. I know that you are there, somewhere in myfortress. I know you keep company with traitors and stand in the shadow of the Collegia Titanica’s god-machines. Faced with such odds, I am speaking to you for the last time. And I say to you again that this fortress will not serve the interests of our unloving father or his renegade Warmaster. But, Captain, I was wrong when I told you that the Schadenhold would never fall. Idriss, it willfall…’

With that the Warsmith locked off the channels and initiated the trigger for both teleporter and detonators. Taking his position amongst Nicodemus and the Iron Warriors on the transference tablets, Dantioch straightened his cloak. Sealing his mask, the Warsmith blinked about the darkness within and felt the unnatural pull of the warp on his armour. Somewhere in the distance he fancied he heard the first of the detonations: massive explosions, ripping through the strategic weaknesses of the fortress foundations. With his eyes closed and the horrors of teleportation about him, Dantioch imagined what he had always known he could never see.

The fall of the Schadenhold. Its literal fall from the ceiling of the cavern. Trillions of tonnes of rock and devious architecture falling to the rocky floor, taking with it the thousands of traitor Iron Warriors and Imperial soldiers that had secured the Schadenhold’s defeat. The fortress’s final defiance, issued in gravity, fire and stone: falling and crushing beneath it, in a behemothic mountain of blood and rubble, the mighty Omnia Victrumand the colossal god-machines of its undoing.

UNSEALING HIS MASK, Dantioch cast his eyes across the flight deck of the flagship Benthos. The deck was largely empty; most of the cruiser’s Warhawks and Stormbirds had been involved in deployment and aerial attacks on the Schadenhold. The Stormbird around which the Iron Warriors had materialised was pale green and bore symbols and flourishes marking it out as belonging to the Sons of Horus – Hasdrubal Serapis’s personal transport.

Tarrasch marched down the Stormbird’s ramp carrying a teleport homer. Dantioch had ordered the device secretly planted on the vessel during their meeting with Krendl and the Sons of Horus captain in the Grand Reclusiam.

‘How are we going to get to the bridge?’ asked Chaplain Zhnev.

‘With as little bloodshed as possible,’ the Warsmith told him. ‘This is the 51st Expedition’s flagship. Iron Warriors are a common sight among its decks. Let us be that common sight.’

‘What about him?’ Tarrasch asked of Tauro Nicodemus. Despite the soot and gore, the brilliance of the Ultramarine’s armour still shone through.

‘The crew will not question a Legiones Astartes.’

Marching out purposefully across the flight deck, Dantioch was followed by his loyalist compatriots. The Space Marines fought their desire to hold their bolters at the ready, opting for more casual or ceremonial poses. Brother Toledo and Sergeant Ingoldt carried the limp plate of the Venerable Vastopol between them, lending the infiltrators even less the appearance of an attacking force.

There were virtually no Legiones Astartes left aboard the vessel, almost every Iron Warrior being committed to the depths of the planet below. Largely the Space Marines encountered regimental staff and the cruiser’s multitudinous crew. Few among these mortals allowed their eyes to linger on the demigods – especially under Krendl’s brutal regime – and their passage to the command deck was uneventful. Dantioch’s strategy had been so bold and audaciously executed that none aboard the Benthos, even for a second, entertained thoughts that they were under attack.

Their silent, uneasy approach to the bridge was shattered by an unexpected klaxon. Bolters came up and the Iron Warriors fell immediately into defensive positions.

‘As you were,’ Dantioch instructed.

The loyalists could hear the thunder of power armoured boots on the deck ahead. ‘We are not discovered. We are not under attack,’ Dantioch said. Fighting natural inclination and the brute vulnerability of their situation, the Iron Warriors let their barrels drift back down to the deck. A small contingent of Krendl’s 14th Grand Company veterans marched across an intersection in the corridor ahead. As their footfalls faded, Dantioch turned to his own veterans. ‘By now,’ he told them, ‘survivors on Lesser Damantyne will have reported the devastation below, the loss of Krendl, the Warmaster’s forces and the Omnia Victrum. Whoever is in command will want visual confirmation of such an impossible report. Five fewer brother Legiones Astartes for us to deal with.’
