Rites of Fire

The Rites of Fire were a series of ancient Sith rituals and acolyte initiations that were considered part of the Upekzar Mysteries. Like the High Rites and the Cold Rites conducted by the ancient Sith at other sites along the Circle of Visions, the High Rites were undertaken within an elaborate volcanic cave system and involved the use of the rhak-skuri, an insectoid subspecies of diplura whose pheromones were known to generate nightmare-like hallucinations in certain humanoid species.

In her research into the history of Upekzar during the Jedi Order's search for Abeloth and Ship, Jedi Knight Natua Wan speculated that the cave system that hosted the Rites of Fire, located in the equatorial region of Upekzar, may have been used by the ancient Sith to study and perfect certain means by which Force users could focus their rage and passions into increased mastery of the dark side.
