Adherents of Ohm
From Tardis Wiki, the free Doctor Who reference
The Adherents of Ohm were a secret society on Gallifrey who worshipped Rassilon, Omega, and the Other. They considered Hedin a martyr and used the Crest of Hedin as a symbol.
The Adherents were fully integrated in Gallifreyan society, and according to Vale Endrogan many high positions in society were held by the Adherents of Ohm, including the Deputy-Coordinator of the Celestial Intervention Agency. (AUDIO: Intervention Earth)
