Mierme Unill was a Jedi Master of the Old Republic during the Clone Wars. Until his death during the war, Mierme Unill was Jedi Master to Zett Jukassa. Master Unill was investigating the deaths of Zett Jukassa's parents, Sembric and Ashielle Skamini when he learned of nightmarish visions the young Jedi was experiencing. Hoping that these visions would lead Mierme to the murderers, he worked with Jedi Master Jocasta Nu to piece together these visions. The information the Jedi obtained eventually led Master Unill to the Black Sun agents responsible for the deaths of Jukassa's parents.
