The Solarox was not a large ship by the standards of the Imperial Navy vessels Chetta had served on, but nor was it a tug. Even using the express elevators, it took her several minutes to get to the forecastle, by which point her joints were protesting bitterly and her mood had worsened significantly. She’d been met along the way by the team Captain Arqueba had assembled at her instruction: a dozen Brobantis armsmen and women in midnight carapace, armed with suppression shields and combat shotguns. Thus flanked, Chetta approached the Navigator’s chamber: a heavily shielded, ingrowing barnacle in the ship’s structure, its external walls encrusted with pipes and power cables, and dotted here and there with readouts attended to by the Solarox’s crimson-robed tech-adepts. One of them looked up at the tap-tap-tapping of Chetta’s steel-shod cane on the deck.

‘High lady,’ the adept buzzed in greeting through the voice-synth that had replaced their vocal cords. It was an alteration most likely made by choice rather than necessity, but Chetta didn’t regard the Adeptus Mechanicus’ habit of replacing their body parts with machines with the same distrust or disgust as many humans did. There were many days when she’d have given her right hand for artificial hips, knees and ankles, but for the moment she was still stubbornly determined to stick with her natural body, despite her regular disagreements with it.

Besides, Chetta knew well what it was like to be regarded as a disgusting aberration. Navigators might be essential to the functioning of the Imperium, but that didn’t prevent the ill-informed and overly superstitious from regarding her and her kin as heretical mutants, rather than the finely tuned results of countless centuries of jealously guarded gene-lore.

‘What is the Navigator’s status?’ she asked, eyeing the chamber warily. The walls weren’t coated in frost, which was something – the very worst manifestations of the warp tended to drop the local temperature to something approaching a Valhallan summer.

‘Insufficient data to be certain,’ the adept replied simply.

‘Your best estimate?’ Chetta said. She’d learned long ago never to use the word ‘guess’ around the initiates of the Martian priesthood, since it tended to upset them.

‘There are no indications of abnormal atmospheric conditions within the chamber,’ the adept told her. ‘Readouts suggest a steady temperature of nineteen point two five degrees Celsius, with humidity at thirty-two per cent. However, we have no readings for pulse, respiration or brain activity. The probability of these monitoring mechanisms all failing at once while others are unaffected is approximately seven per cent. Ergo, I believe it is reasonable to assume that Lord Vora has expired.’

‘Marvellous,’ Chetta muttered. ‘The viewing shields?’

‘Still open, high lady.’
