Alien

Time, again. Little enough time. The Callidus concentrated and retched, opening a secondary stomach to vomit up a packet of white, doughy material. With shaking hands, Koyne ripped open the thin membrane sheathing it and allowed air to touch the pasty brick inside. It immediately began to blacken and melt, and quickly the assassin pressed it to the glassaic of the cupola.
The robots were still coming. The shooting had stopped and the Crusaders were advancing down the corridor. Koyne saw the shadows of them jumping on the curved walls, lurching closer.
The assassin sat down in the middle of the room and drew up into a foetal ball, forgetting the face of the civilian, forgetting Gergerra Rei and the Queen Jocasta, remembering instead something old. Koyne let the polymorphine soften flesh into waxen slurry, let it flow and harden into something that resembled the chitin of an insect. Air was expunged, organs pressed together. By turns the body became a mass of dark meat; but still not quickly enough.
The Crusader maniple advanced into the observation cupola just as the package of thermo-reactive plasma completed its oxygenation cycle and self-detonated. The blast shattered the glassaic dome and everything inside the cupola was blown out into space. Rei’s guardian machines spun away into the vacuum even as safety hatches fell to seal off the corridor. Koyne’s body, now enveloped in a cocoon of its own skin, went with them into the dark.
