Multiworld

The Multiworld was a leisure planet located on a stabilised fluctuation rift. The rift's temporal properties allowed multiple different versions of the Multiworld to exist simultaneously, each a half-second out of sync with the rest.

The Eleventh Doctor took Amy Pond and Rory Williamshere, but their holiday was interrupted when a Sontaran battleship crashed nearby.

According to the Doctor, the tailors employed by the Multiworld were among the best in the galaxy. (IDW: When Worlds Collide)
