Hedin

Hedin was a member of the High Council of the Time Lords. He was also an old friend of the Doctor.

Biography
Like all Time Lords, Hedin was taken from his family at the age of eight for the selection process in the Drylands. Staring into the Untempered Schism as part of a Time Lord initiation rite, Hedin was inspired by what he saw in the Schism. (PROSE: A Brief History of Time Lords)

Tamasan studied Old High Gallifreyan at the Academy under Hedin. She thought he was a good teacher, albeit with dodgy politics. (AUDIO: Jonah)

Out of sympathy for Omega's plight, Hedin helped carry out Omega's plan to bond with the Fifth Doctor and achieve physical existence once more. He shot Talor with an impulse laser, allowing him to remove the records of Omega's theft of information from the Matrix where he stole the Doctor's bio-data extract. He also planted evidence that framed Lord President, making the rest of the High Council believe he was Omega's ally. When Jerricho attempted to kill the Doctor to prevent the bond from taking place, Hedin sacrificed his life to save the Doctor, allowing Omega to complete the bonding. (TV: Arc of Infinity)

Later, the Adherents of Ohm, a cult of Omega on Gallifrey, considered him a martyr and used the Crest of Hedin as a symbol. (AUDIO: Intervention Earth)

Altered reality
In an altered state of reality, Hedin was a senior Time Lord and wrote a biography of Omega. He accompanied the Magistrate on his mission to investigate the source of the Effect in the far future. As part of that crew he worked to map the Needle to locate the lifeforms living there and the specific source of the Effect. After the Doctor defeated Omega, who was responsible for the Effect, Hedin began writing the biography from scratch. (PROSE: The Infinity Doctors)

Appearance
Hedin had a long, thin face. (PROSE: Arc of Infinity)
