Object
Walled City Underground Tunnels
A dangerous subterranean network beneath the walled city, used by Vicki alone to reach the TARDIS and by Ian to navigate between chambers. Partially obscured by shifting sands, these tunnels serve as an escape route from the Mire Beast and Dalek-infested sections in The Chase Part 2 (ep_sea_ser_doctor_who_s02_e31).
