Stoyn

Quaddrigger Stoyn was a Time Lord engineer who was decommissioning the Doctor's TARDIS when the First Doctor and Susan Foreman first stole the machine. Stoyn travelled with them to Earth's moon. (AUDIO: The Beginning)

Stoyn stayed on the Moon for some time but found that the noise of too many people disrupted his focus. Stoyn left the Moon and found a sentient planet far away from civilisation. The planet created the circumstances from which Stoyn could track the Doctor's travels through space, and he created a wormhole leading the TARDIS to him. When the TARDIS arrived, Stoyn encountered the Second Doctor, Jamie McCrimmon and Zoe Heriot. (AUDIO: The Dying Light)
