The Imaging door wheezed shut, presumably as Harrow placed her hand upon the pedestal, and the Response door ground open: the skeleton stepped forward, bone feet crunching on a carpet of other bones. As it stepped through, the door plunged shut behind it, and the little light next to Occupied turned red.
Whatever happened next happened pretty goddamn fast. The lights in Response flared as the vents started choking out cloudy puffs, obscuring the far wall: she pressed herself so close to the glass that her breath made it misty and wet. There was no sound from within, and there should have been (it must have all been soundproofed) which simply made it all the more absurd when something enormous and misshapen came raging out of the fog.
It was a bone construct, she could tell that much. Grey tendons strapped a dozen weirdly malformed humeri to horribly abbreviated forearms. The rib cage was banded straps of thick, knobbly bone, spurred all around with sharp points, the skull—was it a skull?—a huge knobble of brainpan. Two great green lights foamed within the darkness there, like eyes. It had way too many legs and a spine like a load-bearing pillar, and it had to crouch forward on two of its heavyset arms, fledged all over with tibial spines. The exterior arms were thrust back high, and she could see now that they did not have hands: just long slender blades, each formed from a sharpened radius, held at the ready like a scorpion’s tail. It rampaged forward; Harrow’s skeleton patiently waited; the construct fell on it like a hot meal, and it disintegrated under the second blow.
The construct turned its awful head toward the window, fixed its burning green gaze on Gideon, and got very still. It lumbered toward her, gaining speed, when the red light for Occupied turned green: there was a low and doleful parp from some klaxon, and then the construct dissolved. It became soup, not bones, and it moved as though sucked into some small grating toward the centre of the room. It was totally gone, along with all the fog, when Imaging sprang open and Harrow found her cavalier with her jaw dropped open.
