He was also the Doctor's oldest friend. They attended the Academy together, and though they'd had their differences in the past, Larna saw that they clearly loved each other. They were the only members of the High Council less than two thousand years old.
Behind the scenes
- The Magistrate is obviously intended to be an incarnation of the Master, though this is never stated in-text. The man with the rosette, who was also intended to be the Master, was also described as having "a sallow face and a small, pointed black beard".
- The War King in The Taking of Planet 5 is intended to be the Magistrate; he remembers to Homunculette an exchange between the Doctor and Sontar seen in The Infinity Doctors. The Book of the War also later hinted that the War King was the Master and War Chief.
