Mort thought that history was thrashing around like a steel hawser with the tension off, twanging backwards and forwards across reality in great destructive sweeps.

History isn’t like that. History unravels gently, like an old sweater. It has been patched and darned many times, reknitted to suit different people, shoved in a box under the sink of censorship to be cut up for the dusters of propaganda, yet it always—eventually—manages to spring back into its old familiar shape. History has a habit of changing the people who think they are changing it. History always has a few tricks up its frayed sleeve. It’s been around a long time.

This is what was happening:

The misplaced stroke of Mort’s scythe had cut history into two separate realities. In the city of Sto Lat Princess Keli still ruled, with a certain amount of difficulty and with the full time aid of the Royal Recognizer, who was put on the court payroll and charged with the duty of remembering that she existed. In the lands outside, though—beyond the plain, in the Ramtops, around the Circle Sea and all the way to the Rim—the traditional reality still held sway and she was quite definitely dead, the duke was king and the world was proceeding sedately according to plan, whatever that was.

The point is that both realities were true.

The sort of historical event horizon was currently about twenty miles away from the city, and wasn’t yet very noticeable. That’s because the—well, call it the difference in historical pressures—wasn’t yet very great. But it was growing. Out in the damp cabbage fields there was a shimmer in the air and a faint sizzle, like frying grasshoppers.

People don’t alter history any more than birds alter the sky, they just make brief patterns in it. Inch by inch, implacable as a glacier and far colder, the real reality was grinding back towards Sto Lat.
