## At a glance

- The Mountain Fold waits where the drawn ridges nearly meet. The Lancaster silhouette gives weight to a gap-reading test. A changing pattern and opposing draft ask you to preserve space, not merely survive the current volley.

- Fictional NPC · not a historical pilot, commander or combat record.
