As she stepped through the door, he caught her arm and dragged her to one side, behind the cover of two other troopers -Judith and Smith—who were staring down the sights of their pulse-rifles towards the end of the corridor. Chaline noted that they also carried proton weapons slung at their sides, ready to be snatched up. Their initial choice of pulse-rifles was obviously to prevent inflicting too much damage, since the base was merely an inflated dome layered with resin-bonded regolith, and all the interior walls consisted of expanded plasgel which, though enough to block sound and create the illusion of privacy, would hardly stop a determined punch.

‘Back to the chamber.’ Villaeus gave her a shove. ‘U-space signatures all over the base—we’ve got company.’

Chaline hesitantly began moving, glancing nervously behind as the three Sparkind kept up with her. Then she heard pulse-rifle fire, yells echoing and a tearing sound. At that moment Villaeus obviously received directions over com, as he turned suddenly to face down the corridor. Chaline tuned in on the military frequency of Sparkind augs. She could not broadcast that way, but she could listen.

SK5: Confirmed hostile — two civs down in North Section.

SK1: Recoverable?

SK12: In a bucket maybe.

SK11: PRs kill ineffective, but do delay the fuckers, going over to PF.

SK1: Contact, hundred yards, three o’clock on corridor’s twelve.

SK1 was Villaeus himself. Chaline picked up her pace, admiring the way the three others kept themselves focused down the sights of their weapons while moving smoothly backwards. There came a whooshing roar she recognized as a proton weapon firing. A subprogram in her gridlink offered up the news that PR stood for pulse-rifle and PF for proton fire—a more correct definition than the old, and now dying-out, misnomer ‘APW’, since these weapons fired field-accelerated protons not ‘antiphotons’.

SK2: Go PF?

SK1: Civs that way . . . twenty yards, pick it up.

Villaeus turned to her urgently. ‘Run!’

At that moment, a series of swordlike spikes stabbed through the righthand wall of the corridor, then the wall itself caved in and something monstrous avalanched through. A giant silvery-grey beetle head grazed the ceiling, emerging above a divided thorax. The creature came down with a clattering crash, multiply jointed limbs starring out from its body to tear into the walls, ceiling and floor. Once centrally located, it began pulling itself along the corridor towards them. The three troops opened fire, but it moved horribly fast—seeming almost designed for manoeuvring in these corridors. In the midst of her shock, Chaline recognized distinct similarities between this creature and a manufactured beast whose remains she had seen on the planet Samarkand.

SK1: Concentrate fire on the head.

The shots burned holes through the monster, and smoke came billowing out from it. It slowed briefly, but nubs like globules of mercury filled up the cavities, quickly skinning over, and then it came on as before.

SK2: We’ve got another —
