Mirru, a male Twi'lek, resided on the planet of Ord Mantell during both the civil war period and the Cold War era between the Galactic Republic and the reconstituted Sith Empire. In approximately 3643 BBY, he came across information regarding an impending road ambush involving bombs, orchestrated by the Mantellian Separatist Movement. He attempted to warn the Republic forces about this approaching danger; however, he was dismissed from their base due to their disbelief. Nevertheless, the Republic reassessed the information he provided and dispatched a promising sergeant to obtain it. Initially doubtful, Mirru ultimately agreed to share his intelligence in return for a substantial sum of credits.
