Planet (Season 17 Launch Trailer)
From Tardis Wiki, the free Doctor Who reference
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.
