Sisterhood of Karn
The Sisterhood of Karn was a female society. They were dedicated to protecting the Sacred Flame, which produced the Elixir of Life. This Elixir gave the Sisterhood extended life. It could also be used to heal serious injuries and, in some cases, resurrect the dead. With special preparation, a varient of the Elixir could actually trigger a Time Lord’s regeneration in cases where the Time Lord was too severally injured to regenerate normally. This varient could influence both the physical and personality traits of the incarnation.
The Sisterhood was also very influential in the hunt, trial, and execution of the renegade Time Lord Morbius.
