Colony's Toxic Extraction Gas (Supply System)
Toxic gas extracted from the Labour Centre's gas mine and distributed through the colony's pipe infrastructure. Workers endure chronic exposure and acute poisoning from leaks, while Macra creatures steal the gas directly from supply pipes, revealing their parasitic dependence on human labor. The gas triggers alarms, forces protective gear use, and is restricted to specific areas (e.g., the Pipe Room and forbidden shaft). Observed by the Doctor and Polly through portholes, its theft by the Macra exposes their hidden control over the colony's resources.
