Erindra

Erindra was the home planet of the Gadot. The Doctor visited the planet several times, including in his third and fourth incarnations. Marsh was sent there to obtain footage of the mating rituals of the Gadot, where he met the Fourth Doctor. Later on, Marsh returned to try and obtain footage of the Fourth Doctor, and met the Third Doctor and Jo Grant. (AUDIO: Waiting for Gadot)
