Jubilee Line

Soldiers in Goodge Street Ops Room watch the Underground map light up as black fungus engulfs Euston Square and pushes toward King’s Cross on active lines. The Jubilee Line stands absent, unmarked and unbuilt in this era, its path free of the advancing blight. This empty route on the glowing display sharpens the soldiers' dread, pinning the threat to existing tunnels while hinting at untapped vulnerabilities beneath London.
