The Grim Wall is known for its vast line of dense asteroids that creates a natural barrier between Federation and Klingon space. But on the Pilgrim route, the only natural passage within the Grim Wall, reports of subspace anomalies have caused significant disruptions. Reports also suggest Klingon patrols have been probing the Federation side of the Grim Wall, exploiting the disruptions for tactical advantage.

Starfleet has assigned the USS Himalaya to investigate these anomalies and ensure the Pilgrim Route remains operational while safeguarding Hecate Station. The ship’s engineering focus is crucial for understanding and potentially neutralizing the anomalies.
