‘When translation occurs, there will be a massive exothermic reaction. Stand well back. Better still, leave the chamber.’ Praetor had moved into position. When he turned the novitiate was standing downcast before him.

‘I am tempered in Vulkan’s forge, sister. I have no need of benediction.’ Praetor looked up. ‘Priest, bring forth the relic. Our time is almost up.’

A dull explosion echoed through the convent-bastion walls all the way to the sanctum. Luminal red bathed the chamber from the tactical console. The outer wall had been breached.

Tsu’gan had a decent view of the screen from where he was standing. The ensuing fire-fight was brutal. A familiar form appeared through the carnage of bolter fire and smoke. Celestians fell like porcelain statues, shattered by its irresistible force.

‘The machine has broken through.’

It scythed through the defenders, crushing tanks and swatting Battle Sisters aside, until it reached the inner gate. Flamers and melta guns were brought up, but nothing fazed it. If anything, the daemon-engine looked bigger, a mutating hulk whose unnatural flesh strained at its corporeal bonds. Tsu’gan’s eyes narrowed when he caught something through the melee. Before he could analyse it further, a stray explosion killed the pict-feed and the tactical console went dark.

Tsu’gan’s eyes met his sergeant’s.

It will be here soon.

Already, the heavy thump of the daemon-engine’s feet could be heard hammering up the corridor towards them.

Praetor’s face was solemn. None would survive. But retrieve the reliquary and it would all be worth it.

‘Now, priest.’

Father Lumeon looked nonplussed. ‘It is before you, Astartes. Sister Evangeline is the relic.’

What might have been anger crossed Praetor’s face. ‘Don’t mock me, priest. If you’ve lost your mind to Chaos, I’ll vanquish you here… now.’

‘Evangeline is the relic, a living relic! She beheld a vision from the Emperor on Earth and it has awoken her grace.’

Praetor saw the truth in the priest’s eyes, and beseeched Vulkan for his strength.

‘Then we have a problem.’

Father Lumeon was shaking his head. ‘No, no. You’re here now. Rescue Evangeline. The rest of us do not matter. You must do this, lord. I beg of you!’

Praetor ignored the priest’s pleas, addressing his Firedrakes instead. ‘Secure the corridor. Firepoints at every ingress.’

Gathimu and Ankar waited for the force-shield to deactivate again then lumbered through the doorway.

‘Astartes, what are you doing? The living relic–’

‘Is a girl, and thusly will not survive teleportation to my ship.’ Praetor spoke harshly. He wasn’t angry at Lumeon, thrusting the serene-looking novitiate towards him desperately. He was angry at the situation and the fact they faced a foe he knew they couldn’t best with strength of arms. Herculon Praetor was not used to such impasses.
