Disciples of Saxon
From Tardis Wiki, the free Doctor Who reference
The Disciples of Saxon were a cult who worshipped The Master. It is believed they were formed during the era of The Sound of Drums and Last of the Time Lords, then went on to revive The Master in The End of Time with the potions of life. He had prepared them to do so should he be killed. In the end of Last of the Time Lords, a hand can be seen collecting The Master's ring which was in fact a hand belonging to a member of the Disciples of Saxon.
