An unnamed planet was visited by the Fourth Doctor in the middle of August as he attempted to get "a few months' rest" in his TARDIS.
The planet had a hazy magenta sky and, around the area in which the TARDIS had landed, was covered in Earth-like trees and shrubbery.
The planet seemed to play host to a disembodied voice, which, on the Doctor's visit, woke him from his rest to warn him of a future encounter with the Daleks before wiping his memory of the conversation, prompting him to observe that it was a "noisy universe" and depart from the planet.
