Tebediatroculozan

Tebediatroculozan was a Time Lord. He was a member of the richest and most powerful houses on Gallifrey. He went to the Academy with the First Doctor, although they didn't know each other well. He was envious when the Doctor left Gallifrey, wishing that he had gone with him.

He was ill during the Sontaran invasion of Gallifrey, and was monitoring lichen growth on Verana Delta when the Daleks invaded. (PROSE: Seven Deadly Sins)
