‘Whatever happened must have happened fast, then,’ Chetta said, more for the benefit of the others around her than anything else. She looked sideways at the sergeant and pointed at the outer blast door in front of them. It appeared ludicrously solid, but it wasn’t a Navigator’s frail frame that it was intended to contain. ‘Remain here, and shoot anything that comes out of that door unless you’re absolutely certain that it’s me.’

‘And if we think it’s Lord Vora, high lady?’ the sergeant asked.

‘Shoot it anyway,’ Chetta grunted, walking forwards. ‘It’s the only way to be sure.’ That had happened once, on one of her first voyages. Old Scara had ridden them through a warp storm, then when the time came to hand over to the next shift and he’d emerged from the chamber, something – some thing – made of torn flesh and jagged bone spurs had started to claw its way free from his skin. Three ratings had died before someone had managed to turn a heavy bolter on it, and even then it had nearly got to Chetta to open her throat with its teeth before it had finally been brought down.

She barely thought about it, these days. She’d seen far worse inside the chamber.

The first blast door slid aside and Chetta stepped through it, then gathered her robe around her as it slid shut behind her. She’d never yet had an item of clothing get caught, but it remained a tiny, irrational fear of hers, one that not even all her years of starfaring could shake.

The blast door in front of her opened, and Chetta took a cautious step into the Navigator’s chamber.

It wasn’t a large space, for a Navigator was required to do very little in there that involved any form of physical activity. It was dominated by the throne: an imposing seat of metal and animal leather, utilitarian yet menacing. Chetta absent-mindedly tugged her robe well clear of the closing second door and scanned the walls and ceiling. They were largely bare metal, and she could see nothing out of place there, no gibbering creature of malice and shadow waiting to spring the moment her attention was diverted. With that precaution taken, she stepped forwards cautiously to inspect the throne’s occupant.

Vora Brobantis was slumped in the seat, and quite definitely dead, if the trails of blood leaking from his nose and ears were anything to go by. Chetta prodded him suspiciously with her cane, but he didn’t spring up and try to murder her while screaming warp-riddled heresy.

‘Thank the Emperor for small mercies,’ Chetta muttered. Vora was dead, sure enough, but at least it looked like he might stay dead. Such things were never entirely certain, when the warp was involved.
