In the dark and the rain, he couldn’t even see the mighty structure. No beacon-lamps to guide him, no searchlights to cling to. Death, like the darkness, was closing.

The bells were tolling.

Men screamed.

Bostok ran, his vision fragmenting in sheer terror, the pieces collapsing in on one another like a kaleidoscope.

Got to get away… Please Throne, oh pl–

Earth became swamp beneath his feet, and Bostok sank. He panicked, thinking he was about to be taken, when he realised he’d fallen into an earth ditch, right up to his chin. Fighting the urge to wade across, he dipped lower until the muddy water reached his nose, filling his nostrils with a rank and stagnant odour. Clinging to the edge with trembling, bone-cold fingers, he prayed to the Emperor for the end of the night, for the end of the rain and the cessation of the bells.

But the bells didn’t stop. They just kept on tolling.

Three weeks later…

‘Fifty metres to landfall,’ announced Hak’en. The pilot’s voice sounded tinny through the vox-speaker in the Chamber Sanctuarine of Fire-wyvern.

Looking through the occuliport in the gunship’s flank, Dak’ir saw a grey day, sheeting with rain.

Hak’en was bringing the vessel around, flying a course that would take them within a few metres of Mercy Rock, the headquarters of the 135th Phalanx and the Imperial forces they were joining on Vaporis. As the gunship banked, angling Dak’ir’s slit-view downward, a sodden earth field riddled with dirty pools and sludge-like emplacements was revealed. The view came in frustrating slashes.

Dak’ir was curious to see more.

‘Brother,’ he addressed the vox-speaker, ‘open up the embarkation ramp.’

‘As you wish, brother-sergeant. Landfall in twenty metres.’

Hak’en disengaged the locking protocols that kept the Thunderhawk’s hatches sealed during transit. As the operational rune went green, Dak’ir punched it and the ramp started to open and lower.

Light and air rushed into the gunship’s troop compartment where Dak’ir’s battle-brothers were sat in meditative silence. Even in the grey dawn, their bright green battle-plate flashed, the snarling firedrake icon on their left pauldrons – orange on a black field – revealing them to be Salamanders of the 3rd Company.

As well as illuminating their power armour, the feeble light also managed to banish the glare from their eyes. Blazing red with captured fire, it echoed the heat of the Salamanders’ volcanic home world, Nocturne.

‘A far cry from the forge-pits under Mount Deathfire,’ groaned Ba’ken.

Though he couldn’t see his face beneath the battle-helm he was wearing, Dak’ir knew his brother also wore a scowl at the inclement weather.

‘Wetter too,’ added Emek, coming to stand beside the hulking form of Ba’ken and peering over Dak’ir’s broad shoulders. ‘But then what else are we to expect from a monsoon world?’

The ground was coming to meet them and as Hak’en straightened up Fire-wyvern the full glory of Mercy Rock was laid before them.

It might once have been beautiful, but now the bastion squatted like an ugly gargoyle in a brown mud-plain. Angular gun towers, bristling with autocannon and heavy stubber, crushed the angelic spires that had once soared into the turbulent Vaporis sky; ablative armour concealed murals and baroque columns; the old triumphal gate, with its frescos and ornate filigree, had been replaced with something grey, dark and practical. These specific details were unknown to Dak’ir, but he could see in the structure’s curves an echo of its architectural bearing, hints of something artful and not merely functional.
