Lonaste, a female Ugnaught who worked as a miner, resided in Ugnaught Town on the planet Bespin during the Galactic Civil War. She came to the conclusion, based on intercepted communications and alerts, that the Galactic Empire was poised to seize control of the city. Despite her warnings to the Ugnaught clans, they dismissed her concerns. As the Imperials arrived and initiated their takeover of the city, Lonaste and her clan endeavored to flee. Accompanied by her cousin Beetase, she ventured to the platforms in search of a starship. Yoxgit pursued them with the intention of shooting them, as he sided with the Empire's assertions regarding the provision of supplies to the miners and opposed Lonaste's clan. However, before he could act, one of Lonaste's aunts incapacitated him, enabling their secure departure from the planet.
