Seeking to expand his territory, the ancient Tionese despot Xim began exploring the Si'Klaata Cluster-and for the first time, encountered a force that could challenge him. This region belonged to the Hutt Empire. Although young, the Hutt Empire had already grown immensely powerful through its criminal enterprises, helped by the long lifespan of the Hutts.
The Hutts correctly assessed the threat Xim presented and poured resources into fighting him near the planet Vontor. Despite their strength, the Hutts were not certain of victory until they discovered the Si'Klaata Cluster was home to several other powerful species, including the Nikto, Klatoonians and Vodrans. In a typical gambit, the Hutts managed to persuade these three species to sign the Treaty of Vontor, which bound them to the Hutts in perpetual slavery.
With these additional forces, the Hutts overwhelmed Xim at the third battle of Vontor. Xim died a Hutt prisoner, leaving his vast holdings and territory free for the taking.
