Slyne

In an alternative timeline, Slyne was the Castellan of Gallifrey. He was concerned for Romana's safety and assigned Lukas to guard her. He didn't particularly like Romana. He noticed that she and Narvin were different to what they were before the assassination attempt. (AUDIO: Emanciptaion)

He called Romana away from a science conference for her to meet Kavil. (AUDIO: Evolution) He later led the expedition to Leela's township to get Lord Zakar back from her. After Narvin played the footage of Zacker's orders to commit murder, he arrested Zakar. (AUDIO: Arbitration)

When Romana called the Chancellery Guard, he warned the Daleks of their firepower and wanted to know who they were. He called them stupid machines and wondered where they came from. The Daleks wanted to keep him them to disrupt the Guards confused. Romana told him the Daleks' one weakness, their Eyestalk. He declared war upon the Daleks but later negotiated an alliance with them. (AUDIO: Extermination)

He piggybacked from his original Gallifrey through the Axis to Romana's Gallifrey with K9 Mark II, and brought the Daleks to this universe. He supported re-electing Romana II to be president upon her return. He was the anomaly that the Daleks went to find. He tricked Romana into deploying her technological cure to the Dogma Virus, incapacitating all other Time Lords to make way for his new masters. After the Matrix doors that they used were closed by Lady Trey, Slyne was betrayed by the Daleks, who exterminated him. (AUDIO: Ascension)
