Voord homeworld
From Tardis Wiki, the free Doctor Who reference
The Voord homeworld was the home planet of the Voord. Caleera destroyed it with a psychic attack, (AUDIO: Scenes From Her Life) prior to the 1970s during the Humanian Era, a violation of established history. The surviving Voord to form a survival flotilla. (AUDIO: Beachhead)
After encountering the flotilla in Stegmoor, the Eighth Doctor visited the Voord homeowlrd and found chronon traces of Caleera's TARDIS. (AUDIO: Scenes From Her Life)
Behind the scenes
Though it does not say so directly, the storyline and dialogue in the Voord's debut story The Keys of Marinus does not suggest that they originate elsewhere other than Marinus.
