A v0.1 rough outline, freely adapted from A Hollow Tree (2023) — the walk
north that never arrives, and a predator that imitates. Everything else
comes out of the system: a 1962 reserve entry that was never cancelled,
forty-one people looping eleven duplicated miles, and Borrowed Authority
as a detector that can only tell filed from unfiled.
Uses existing bestiary entries only. Marked not-runnable: no pregens,
read-aloud, handouts, Act Four exposure model or playtest yet.
