Dahz Thulaka was a female Twi'lek Jedi Master who served the Jedi Order during the Golden Age of the Jedi. An alchemist, Thulaka was interested in using living flesh to create new life, a technique some within the Order frowned upon. A researcher at Anil Kesh, Thulaka's research was regarded as a potential medical breakthrough by the Temple Master of Mahara Kesh, Braz Morphius.
