Haronn was a male Twi'lek who held a position on the Corellian Council during the period of the Galactic War that saw conflict between the Galactic Republic and the re-emergent Sith Empire.
After the conclusion of the Cold War, Haronn was there when the Council chose to side with the Empire in the year 3640 BBY. Despite this, he and some other Council members chose not to serve the Empire, remaining dedicated to the Republic. When Corellia was invaded by the Empire, Haronn made the choice to depart the planet alongside various Republic military personnel. However, his transport was brought down while flying over Imperial-controlled territory in the eastern shipyards. Haronn utilized an escape pod to eject, and was subsequently saved by a hero of the Republic.
