The Sisterhood of Sibi is a religious order of Tsuranuanni devoted to Sibi, the goddess of death. They wore plain black robes and maintained a black, featureless appearance among their priestesses.
Their members were present in any event, affirming that many will die.
Also among their ranks are the Mad Dancers, warriors who served death, whose mere touch was fatal, as they leaped and gyrated until exhaustion claimed their lives.
