‘What happened?’ His throat felt raw and abrasive, and he croaked the words. Fugis stepped away from Dak’ir’s medi-slab to check on the instrumentation. He limped as he walked, a temporary augmetic frame fitted over his leg to shore up the break he had sustained in his fall. Stubborn to the point of bloody-mindedness, nothing would prevent the Apothecary from doing his work.

‘Stratos is saved,’ he said simply, his back to the other Salamander. ‘With the Speaker dead and our flamers restored, the insurgents fell quickly. The storms lifted an hour after we returned to Aereon Square,’ he explained. ‘Librarian Pyriel arrived twenty minutes later with the rest of the company to reinforce N’keln, who had taken the wall and was already en route to Aura Hieron…’

‘But too late to save Kadai,’ Dak’ir finished for him.

Fugis stopped what he was doing and gripped the instrumentation panel he’d been consulting for support.

‘Yes. Even his gene-seed was unsalvageable.’

A long grief-filled silence crept insidiously into the room before the Apothecary continued.

‘A ship, Stormbird-class, left the planet but we were too late to give chase.’

The rancour in Dak’ir’s voice could have scarred metal.

‘Nihilan and the other renegades escaped.’

‘To Vulkan knows where,’ Fugis replied, facing the patient. ‘Librarian Pyriel has command of Third Company, until Chapter Master Tu’Shan can appoint someone permanent.’

Dak’ir frowned.

‘We’re going home?’

‘Our tour of the Hadron Belt is over. We are returning to Prometheus to reinforce and lick our wounds.’

‘My face…’ Dak’ir ventured after a long silence, ‘I want to see it.’

‘Of course,’ said Fugis, and showed the Salamander a mirror.

Part of Dak’ir’s facial tissue had been seared away. Almost half of his onyx-black skin had been bleached near-white by the voracious heat of the melta flare. Though raw and angry, it looked almost human.

‘A reaction to the intense radiation,’ Fugis explained. ‘The damage has resulted in minor cellular regression, reverting to a form prior to the genetic ebonisation of your skin when you became an Astartes. I cannot say for certain yet, but it shows no sign of immediate regeneration.’

Dak’ir stared, lost in his own reflection and the semblance of humanness there. Fugis arrested the Salamander’s reverie.

‘I’ll leave you in peace, such as it is,’ he said, taking away the mirror. ‘You are stable and there’s nothing more I can do at this point. I’ll return in a few hours. Your body needs time to heal, before you can fight again. Rest,’ the Apothecary told him. ‘I expect you to be here upon my return.’

The Apothecary left, hobbling off to some other part of the ship. But as the metal door slid shut with a susurrus of escaping pressure, Dak’ir knew he was not alone.

‘Tsu’gan?’

He could feel his battle-brother’s presence even before he saw him emerge from the shadows.
