Zypedria

Zypedria (zigh-peh-dree-uh) is the home world of the Zypedrians, mentioned briefly in Terror of the Zypedrians. The planet was indirectly part of a battle in 2024 against Earth, which led to a retreat after being defeated by the Human-Venusian Alliance.

The planet remained mostly untouched until 4246, when a stray Time War refugee crash-landed on Zypedria. The scientists forced him to use his knowledge and derelict TARDIS to create a single machine, not unlike a Vortex Manipulator, which would allow them one last chance to destroy the man responsible for everything: Christopher Davola.
