Deindus

From Tardis Wiki, the free Doctor Who reference

Deindus was the homeworld of the Deindum. Irving Braxiatel called it an "unremarkable chunk of rock". (PROSE: Winging It) Genetic material from over fifty species travelled through a fissure and reacted with primordial soup on Deindus, resulting in the creation of the Deindum. (AUDIO: Resurrecting the Past)

During the Deindum War, Deindus had the largest concentration of Deindum forces, along with Maximediras.

Bernice and Peter Summerfield travelled to Deindus in the future using a time ring, at a point long after the Deindum had been defeated. They spent some time there, noting how silent the winds on the planet were. (AUDIO: Escaping the Future)
