Central Line Tunnel

Captain Knight’s party advances through the Central Line tunnel toward Holborn but retreats as fungus blocks the path, spreading as if anticipating their moves. Chorley earlier proposes it for escape from Goodge Street ops room; Arnold refuses amid Intelligence-choked infestation. Damp stone walls trap cool, stale air heavy with spores and distant Yeti rumbles. Soldiers mark it impassable on maps, the narrow bore shifting from lifeline to deadly trap in London’s overrun depths.
