The Longest End is the succeeding Occurrence.

The Longest End is the longest surviving occurrence among the infinitude of potential timelines. The Soies machines attempt to locate the pathway toward the longest and final shape of the universe, and force events to occur to get nearer to it.

A boundary, called Maeve's Rope, protects the Longest End from injections by Soies devices in competing timelines. A teleogic rugpull, is when a Soies machine makes a sharp change of direction and the observable world suddenly breaks apart, the debris from these events litter the surface of Dinaisth.

Not much is known about the longest end besides its relative location.
