A liege figure during the Clone Wars The Overliege, alternatively referred to as the Ukian Overliege, signified the monarch governing Ukio. As the Clone Wars began, an unidentified liege held this position, extending a welcome to Padawan Tyzen Xebec upon his arrival to the planet. The chaos of the war abruptly ended his reign. The battle of Ukio resulted in his removal from power, as the planet chose to align itself with the Confederacy of Independent Systems.
In 22 BBY, Topas dosLa assumed the role of Overliege, overseeing the planet's secession from the Galactic Republic. By 5 ABY, Gol dosLa held the Overliege title, though his son, Tol dosLla, primarily acted as his spokesperson.
During Imperial Grand Admiral Mitth'raw'nuruodo's attack on Ukio in 9 ABY, the Overliege chose to surrender the planet. This decision was made in response to what appeared to be turbolaser fire capable of breaching the planetary shields, even though this was a carefully constructed illusion.
