The Demon's Blood ritual was a custom practiced by the Tusken Raiders residing on Tatooine. In this rite, Jedi Order members pursuing enlightenment ventured into the desert to hunt a sand demon and use its blood for anointment; those Jedi who made it back then went to the Tusken Raiders to gain knowledge of their individual path to self-discovery.
During the time of the Cold War, Darth Baras's spy, Sharack Breev, witnessed Nomen Karr's Padawan, Jaesa Willsaam, performing an unusual Jedi ritual at a Sand Demon cave. Subsequently, Baras dispatched his apprentice to Tatooine in search of Jaesa Willsaam. Breev guided the Sith Warrior to Izzeebowe Jeef, who disclosed that Willsaam had undergone the Demon's Blood ritual. Jeef suggested that the Sith apprentice also participate in the ritual.
