Why leverage stops
The World tier makes the Infinite Boundary's place legible: it begins exactly where pushing stops being possible, the same rule reaching its edge rather than a pass granted for convenience.
Where it appears
Treated in
- Part Five — The Standing ThirdsThe World-KinThree figures, and only three, derived rather than chosen: two Culture-Kin sharing a Skein-Kin. The last tier where a push still reaches.
- Part Five — The Standing ThirdsThe Infinite Boundary — Cosmos ScaleThe one figure with no healthy pole and no failing pole. A pole has to be read from somewhere, and there is nowhere outside this one to stand.
