Were the gabbleducks all that remained of the Atheter when they made their fateful decision to cease to be the intelligent citizens of a technical civilization? Blegg doubted that, else why did this thing, this Atheter AI, want to be taken to where remained those animalistic descendants, the gabbleducks? It was all a mystery that would have to wait for another time, since Blegg had more pressing concerns. He turned away, felt the ground sliding out from underneath him, and saw a black wall descend.

Hiatus.

Blegg stepped out of the VR booth, blinked and looked around him. The staff on the observation deck peered at him warily. Gazing through the screens, he observed that the artefact seemed to have settled back to its previous state.

‘Hourne,’ he said, ‘are you back?’

The AI replied, ‘The artefact has disconnected itself from me, but may reconnect at any time.’

‘Do you have that U-space signature?’

‘I do—it was transmitted to me at the same time as you received it in VR.’

‘You saw all that, then?’

‘I did.’

‘Interesting… about the gabbleducks. Do you believe it?’

‘If it is not actually the truth, it seems a strange and pointless lie to tell.’

‘There was not much resistance, then,’ Atheter observed.

‘Sporadic,’ Blegg replied. ‘Mostly crushed by human fighters bright enough to realize the AI rulers were better at governing than any previous human rulers.’

He turned to another card, saw them laid out all around him like gravestones.

Blegg ran down the seemingly endless corridor, while klaxons shrieked and warning lights flashed. Grieg told him the terrorists were ex Matthew Corporation employees who obtained the planar explosives from a mercenary group who decided on retirement under the new regime and were now selling off their assets. That had been a relief, since from the beginning of the investigation ECS intelligence believed them to have obtained fissile materials. But planar explosives could still do plenty of damage if detonated somewhere critical.

‘Left turn at the end here, second door on your left,’ Earth Central informed him.

Somewhere critical seemed to be snuggled up against the Amaranth Station reactor, or so Draben told the interrogators. Halting by the door Blegg waited a moment.

‘Nothing connected to the door,’ EC assured him.

He opened the door and entered, scanning the room. The reactor cube, five yards on each side, sat in the middle of the room amidst a tangle of cooling pipes and heavy power cables. Control consoles lined one wall, and gratings had been pulled up from the floor when this place was searched earlier.

‘The detonator is solid-state, activated by timer and gravity switch.’

Blegg walked in, studying that part of the reactor where steam pipes exited towards the generators next door. There—beside the pipes. No wonder the earlier searchers did not find it. The bomb appeared to be a pressure and stress analyser bolted across the point where the pipes exited the reactor. He climbed nearby steps up to a catwalk and walked along until standing beside the explosive device.

‘How long have I got?’

‘Four minutes—not long enough to deactivate it.’

Blegg considered that. Running here had been an almost instinctive reaction. He should have transferred himself through U-space to give himself more time. But, then, would another couple of minutes have made any difference? He placed his hand on the bomb. ‘A gravity switch and a timer, you say? Nothing else linked to its attachment to the pipes?’

‘So Draben just told his interrogator, and he seems less inclined to lie now. One moment…’ The AI fell silent for a while, then returned with, ‘It is secured by four bolts. You require a socket drive, which you will find in a toolchest below the catwalk.’

Blegg quickly returned below, found the toolchest and flipped it open. The socket driver, a gun-shaped object with a tool-head that could adjust to fit any bolt, lay amidst a well-used collection of old-style spanners. Ominous, that. He hoped whoever used the device kept it well charged and did not have to resort to the spanners too often. He picked it up and pressed the trigger — seemed okay—and returned to the catwalk. Closing the driver on the first bolt he hoped Draben was not lying. The bolt spun out easily, as did the second and third.

Placing the driver over the fourth bolt Blegg concentrated on his breathing and instilled calm within himself. The gravity switch meant he must keep the bomb to its present orientation. He clamped a hand against it and spun out the last bolt. Discarding the driver behind him, he then carefully eased the bomb away from the pipes.

‘How long?’

‘Two minutes.’

Blegg checked his watch. It would have been nice to be able to transfer himself and the device far from here, but neither gravity nor orientation applied in U-space, so such a transference might trip the switch. Amaranth would be safe; he would cease to exist. He turned slowly and walked along the catwalk to the steps, his martial training enabling him to move smoothly and evenly. Negotiating the steps was more difficult, but he reached the floor safely.

‘You need to get at least two hundred yards from the reactor,’

EC informed him. ‘Outside the door, turn to your left and keep walking. The area has been evacuated.’

The door was latched. Blegg pressed the bomb against the wall to keep it upright, opened the door and held it open with his foot as he entered the corridor beyond. His mouth dry, he continued that sliding walk.

‘How long, how far?’ he eventually asked.

‘Just keep going—I will tell you when to put it down.’

Trust Earth Central?

He checked his watch again. Thirty seconds more and he would put the damned thing down anyway and get out of there. Slowly the digits counted down.

‘Carefully place the bomb on the floor,’ EC told him, only seconds before he intended to anyway.

He squatted, followed instructions. The thing looked precarious propped up against the wall. Standing, he immediately opened that doorway that he, the only human being, could open. The bomb detonated shortly afterwards blowing a hole in the side of the station. No humans died.

Survival.

Thellant’s mind worked with a clarity he had never before experienced. The substructure now cut through the bedrock, from where Coloron’s forces had contained it, and was rapidly spreading through the rest of the arcology. Those people it now subsumed he could control completely, but he left them to some already established program integral to the Jain technology, which made them attack others to either kill or subsume them. Whether they managed to or not did not really concern him. Only the chaos they created really helped, for in the end he knew he could not win here. He was powerful, and potentially able to control this entire arcology, its population, even the whole planet, but that presupposed he would be left alone to achieve such control. Thellant knew the AIs would not allow the substructure to spread beyond this place, no matter the cost. Though it was part of him, because he retained much physical and mental integrity it was a part he could sacrifice and grow again elsewhere. He did not intend to be in this vicinity when the AIs incinerated the arcology.

Peering from the wreckage, Thellant observed the landscape of cooling rock and molten metal at the bottom of the trench. Looking through the substructure now rising in wall cavities, and spreading along ducts, optics and power lines on the other side, he saw Coloron’s forces pulling back—they knew their enemy to be out of containment now. For every ten yards gain he lost five yards to proton fire, but with hand weapons they could not destroy everything the substructure occupied.
