Brotherhood of the Black Petal
From Tardis Wiki, the free Doctor Who reference
The Brotherhood of the Black Petal were a religious order on Strellin known for their skill with stained glass. They consumed the essence of the hallucinogenic dreamflower to become one with nature.
When Daleks crash-landed on the planet, the Brotherhood made them new cases with stained glass whilst keeping Kaled mutants alive in animal carcasses and feeding them with blood. (AUDIO: Order of the Daleks) This incident was recorded in the Dalek Combat Training Manual, compiled and published by the Time Lords during the Last Great Time War.
