The Homeworld (Dot and Bubble)
From Tardis Wiki, the free Doctor Who reference
The residents of the Homeworld sent the young progeny of the wealthy to Finetime, a heavenly colony on their moon.
In contrast to the bright, tropical and pastel coloured cityscapes on Finetime, the Homeworld was heavily industrial, with vast tower blocks and a smoggy, grey sky.
The inhabitants of the Homeworld were later destroyed by the man-traps. (TV: Dot and Bubble [+]Loading...["Dot and Bubble (TV story)"])
