Thane (The Elite)
From Tardis Wiki, the free Doctor Who reference
Father Thane was the head of the Church on Florana in its early history. He was loyal to the High Priest, a Dalek who claimed to be an emissary of God. He heard the Dalek talking to the Fifth Doctor, and admitting that it was not a true god. Realising that he had been used all this time, he killed the Dalek, and tried to use a weapon known as the Cleansing Fire to wipe all non-believers from the face of the planet. He died in the process. (AUDIO: The Elite)
