The Brethren

The Brethren were a group of corrupt monks in Scotland. They could be recognised by their bald heads and orange robes. They were led by Father Angelo.

The Brethren practiced martial arts, though they weren't above shooting people. They might also have trained the Werewolf to fear mistletoe. (TV: Tooth and Claw)

History
Some time in the 1540s, the Brethren discovered the Lupine Wavelength Haemovariform's crashed spaceship and decided to try to help it. They turned away from their God and started to worship the Wolf. They provided hosts and food for the growing werewolf for over three hundred years. In 1879, they also arranged events for Queen Victoria to be bitten to start "the Empire of the Wolf". This plot was foiled by the Tenth Doctor and Rose Tyler, and both Father Angelo and the Wolf were killed. (TV: Tooth and Claw)
