Separatist forces under General Sev'rance Tann arrived on Tatooine after she had been informed by Count Dooku that Boorka, a Hutt living on Tatooine, had valuable information for the Separatists. After stocking up on supplies on the neighboring Kaer Orbital Platform in the Siskeen system, Tann's forces arrived on Tatooine.
First, Tann fought her way through Boorka's guards, impressing him greatly. Boorka agreed to give Tann his information concerning the Decimator, but only if she destroyed the Republic spaceport nearby.
Tann and her droid forces pushed through and overpowered the Republic defenses and demolished the spaceport, succeeding in Boorka's task. The Hutt finally gave up his information, which was that the Republic was building a massive weapon called the Decimator on Eredenn Prime.
