And it came down to four frames; four snapshots of recent history. In one frame the Excession seemed to be rushing out, accelerating out to meet it, in the next the skein/field had wrapped itself almost totally around the ship - at a distance of perhaps a kilometre from ship-centre, though it was hard to estimate - leaving only a tiny hole staring out to the rest of the universe on the opposite side of the ship from the Excession, in the third frame the total cut-off from the universe was in place, and in the next it had gone, and the Fate had moved, or had been moved, thirty light years in less than a picosecond.

How the fuck does it do that? the ship wondered. It started checking that time was still working properly, directing its sensors at distant quasars which had been used as time reference sources for millennia. It also started checking that it was not in the centre of some huge projection, extending its still-stopped engine fields like vast whiskers, feeling for the (as far as anybody knew) unfakeable reality that was the energy grid and minutely - and randomly - scrutinising sections of the view around it, searching for the equivalent of pixels or brush strokes.

The Fate Amenable To Change was experiencing a sense of elation at having survived what it had feared might be a terminal encounter with the Excession. But it was still worried that it had missed something, that it had been interfered with somehow. The most obvious explanation was that it had been fooled, that it had been tricked into moving itself here under its own power or been moved to this position via another tractive force over time. The further implication was that the interval when it had been moving had somehow been expunged from its memory. That would be bad. The very idea that its Mind was not absolutely inviolate was anathema to a ship.

It tried to accustom itself to the idea that this was what had happened. It tried to steel itself to the prospect that - at the very least - it would have to have its mental processes investigated by other Minds to establish whether it had suffered any lasting damage or had had any unpleasant sub-routines (or even personalities) buried in its mind-state during the time it had been - effectively - unconscious (horrible, horrible thought).

The check-time results started coming in.

Relief and incredulity. If this was the real universe and not a projection, or - worse still - something it had been persuaded to imagine for itself inside its Mind, then there had been no extra elapsed time. The universe thought it was exactly the same time as the Mind’s internal clock did.
