Finetime
From Tardis Wiki, the free Doctor Who reference
Finetime was an isolated city where rich children of the Homeworld lived lives of party constantly connected to their Dots. It was surrounded by the Wild Woods, on a planet separate from the Homeworld.
It was inside a protective dome, with strong enough security that the Doctor's TARDIS couldn't land there. (TV: Dot and Bubble [+]Loading...["Dot and Bubble (TV story)"])
