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.

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)"])
