Detention Block Ventilation Secondary Ducts
Narrow metal duct system running along upper walls throughout the Kaled detention block and corridors, forming a secondary network branching from primary airflow shafts. The ducts feature grated surfaces clogged with dust and torn fabric strips, with interiors cramped enough to admit only a child or small adult. Characterized by decades of neglect: rusted seams, trapped stale air pockets, and metallic conditioning system odors. Serves dual purposes—ventilation functionality and escape routes for prisoners and Doctor Who companions.

Purpose
To provide secondary air circulation and, in theory, limited emergency egress between detention cells and service corridors.
Significance
Serves as the only plausible escape route engineered to bypass detainee monitoring. The trio’s decision to trust these rotting passages over the heavily guarded primary exits triggers a climactic sprint against time, testing fragile trust between former adversaries turned reluctant allies.
