Northern Resistance Base (Resistance-Held Territory)

A strategic refuge north of London where a coordinated resistance force battles the Daleks. Described as a destination offering evasion of Dalek patrols and alliances with scattered survivors, this location is framed as essential for survival where isolated cells falter. The Doctor's group is urged to join the resistance here by Susan and David, though the Doctor initially resists due to perceived risks. The base represents a fragile hope for unity and defiance against the Dalek invasion, with whispers of organized holdouts drawing the group forward.
