Saul moved back out into the open, then skirted the wall, studying in his mind a schematic of all the hardware nearby as he progressed. Finally reaching a certain point, he looked up, and noted a mass of optic cables that emerged from the wall above then ran along a beam continuing out of sight somewhere behind him. He leapt up towards it, caught hold and pulled himself over, coming down astride the cables just at the point where they exited the wall.

Here the sheer mass of cables was further distended by a great number of connector plugs all gathered together. Slowly and methodically he checked the codes etched into the side of each plug, till on the eighth one found the optic connection he sought. This plug, however, could not simply be pulled apart, being tightly secured by a ring of screws. Saul pulled it away from the others, drew his pistol and fired a shot. The cable was whipped out of his hand, the shattered plug parting, while the frayed optic cables provided a display of green and yellow laser light. Retrieving the plug, he could now pull it apart. That ensured that the hardwire connection was removed and, when the Traveller VI engine fired up, the EM interference produced would make it impossible to issue radio instructions able to shut it down. Saul propelled himself back to the floor. Time now to stack the dice even further.

Saul waited at the entrance to the tunnel leading through the wall insulation, gazing back at the Arboretum cylinder. How much force could the structural beams here withstand? They were much more widely spaced than would be required for a building on Earth, but would soon be subjected to levels of stress halfway approaching the same. Since he had set the engine to fire up at its maximum, the initial thrust would be in the region of half a gravity. He paused for a moment to make some complex calculations and discovered that, though the massive shaft spindles of the Arboretum and the arcoplexes would take a huge amount of the resulting strain, there would be substantial damage caused to the intervening areas. That was unavoidable, however. As he finished making calculations which confirmed that any internal buildings still under construction – like the Political Office and the cell block – might tear loose from their mountings, he finally sensed that his five construction robots were approaching, and turned to face them.
