A clash transpired between the Confederacy of Independent Systems and the Galactic Republic, an event within the Outer Rim Sieges, which themselves were part of the galaxy-wide conflict known as the Clone Wars. This battle unfolded on the frigid Outer Rim planet of Toola, where a Republic task force, under the leadership of Jedi Masters Kai Hudorra and Simms, engaged in combat with Separatist forces.
Following a prolonged stalemate lasting several weeks, the Jedi initiated an offensive against the enemy's primary generators. They utilized the herbivorous creatures called mastmots as mounts for their assault team, while the remaining troops launched a distracting attack. This strategy proved successful; however, shortly after their triumph, Order 66 was executed. Supreme Chancellor Palpatine of the Republic commanded the clone troopers to eliminate their Jedi commanders, accusing them of treason. Clone Commander Keller instructed his soldiers to obey the order. During the subsequent exchange of fire, Master Hudorra and Simms' Padawan, Noirah Na, made their escape aboard commandeered STAPs, while Master Simms provided cover, sacrificing herself in the process.
Hudorra and Na, in their flight towards Ithaqua Station, were forced to abandon their Single Trooper Aerial Platforms when one of them ran out of fuel. Keller and his soldiers located them and alerted the garrison at Ithaqua to the Jedi's impending arrival. Despite the imposition of martial law, a city-wide curfew, and clone patrols throughout the streets, Master Hudorra successfully infiltrated the city to ascertain the situation with the clones. After discovering the conclusion of the war and the rise of the Galactic Empire, the two fugitive Jedi managed to reach Toola Spaceport and depart on a transport bound for Coruscant.
