Lucazec was a planet located within the Outer Rim Territories. Originally known as Far Thanium, it was absorbed into Xim's empire as he expanded his borders from the Kingdom of Cron. After the fall of the empire in 25,100 BBY, it would eventually join the Galactic Republic. Lucazec was the Fallanassi world of origin. During the Clone Wars the planet was located within Separatist space. The Fallanassi fled the planet when Cassio Tagge tried to recruit them to the Empire.
The Yuuzhan Vong smashed the planet while invading the galaxy.
