Still there was no clear image of it as it moved along the vestibule; all the sensitive cells could discern before they died was a tumour of darker shadow within the lightless chamber. And now the habitat personality was having to divert its attention to the rest of the Orgathй swarm that were slamming their way through other starscraper windows. Emergency pressure locks and muscle membranes were closing throughout the deserted structures, desperately trying to contain the atmospheric breaches.

The Orgathй continued to surge forward into the starscraper, hunting round for concentrations of life-energy to consume. It was spread thinly here, nothing like as rich as the layer beneath the object’s outer surface. Instinctively, the Orgathй barged upwards towards that mammoth source. Flat planes of matter splintered as it hammered through them. Further harsh gusts of gas whistled past. Then it found what it wanted, a solid stream of liquid suffused with life-energy pouring along the core of the starscraper. It moved as close as it could, siphoning the heat out of the thick wall of matter surrounding the stream until the outside began to crack. Then it bored through with a couple of appendages, and immersed their tips in the current. Sweet, vital life-energy flowed back into the Orgathй, replenishing it after its considerable exertions. It settled down and began consuming the apparently infinite torrent, growing in a way impossible before.

Three trucks approached the ring of dilapidated hovels encircling the Djerba’s lobby. Each vehicle had two people inside, a nervous driver and an even more nervous lookout armed with a heavy calibre rifle. They began to nudge along the muddy tracks between the precarious walls, heavy wheels squelching cans and empty sachet wrappers into the ground.

Past the hovels, they pulled up short of the lobby.
