Stoyn
Quadrigger 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. He was angry as he was in the engine rooms when the Doctor made his first journey. He was scared at being on a different planet. When there was a stasis field rleased by the TARDIS, he told the Doctor that he had ruined the Archaeons experiment. He wanted to leave the Doctor on the Moon and take Susan travelling with him. (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. He wanted to drain the TARDIS of its energy. He later asked Zoe to help him build a machine. He was trying to make a Hypercube. (AUDIO: The Dying Light)
Romana decommissioned his Quadrigger station on Gallifrey so that the land could be used to build Battle TARDISes, and remembered her encounters with Stoyn in her two previous incarnations. In her first incarnation she and the Fourth Doctor visited Rome during their search for the Key to Time and tracked the sixth segment there. He presented a play in the streets of Rome called Luna Romana. He found the TARDIS in the temple of Luna and told Romana that he had been to the moon once. He thought that Romana was his only hope.
The Randomiser later took Romana's second incarnation to Rome on the moon. This was a tourist spot recreating ancient Rome, she met Stoyn on the moon. He wanted the Doctor and used some robots to capture him. He showed them pictures of their travels. He made himself a matrix fashet from the component of the TARDIS and could only see the Doctor's travels. He had been on the moon for 2000 years. He accidentally travelled back to the real Rome, after Romana stabilised a time field. He had lost his mind a bit due to this a met the first Romana. He had is many robots that he had on moon and sent them to act in plays. Romana told him how his job was know done by a button in the post type-54s and there was a few temporal mechanics left. He tricked Romana into allowing him into the TARDIS. He used the fifth segment of the key to time to bait the Doctor and Romana to get there. He said that the TARDIS was property of the capitol and wanted to take it back to Gallifrey. He dismantled K9 Mark II as it annoyed him. Romana said that Stoyn was remembered in the academy as an expression for a mistake in engine repair. He waned to rewrite time so that the Doctor wouldn't steal the TARDIS in the first place. He thought that the Doctor and Romana was betraying the legacy of Gallifrey. He was dispersed when operating his controls, by an accident. (AUDIO: Luna Romana)
