During the time of the Clone Wars, a battle occurred on the Outer Rim planet of Florrum. This conflict involved Hondo Ohnaka's pirate gang, with assistance from the Jedi Order, against opposing pirate forces led by the rogue Sith duo of Maul and Savage Opress. These brothers journeyed to Florrum with the intention of establishing a criminal enterprise, offering riches and authority to any pirates willing to betray Ohnaka and align with them. Ohnaka declined to yield, which prompted the brothers to besiege his pirate base.
Soon after, Jedi Masters Obi-Wan Kenobi and Adi Gallia, both belonging to the Jedi Council, arrived to aid the pirates. They had been pursuing Maul and Opress across the Outer Rim. They joined the pirates loyal to Ohnaka in their fight against Maul and Opress, but Gallia was killed in battle by Opress. Kenobi and Ohnaka's group then withdrew, drawing the renegades into an ambush that compelled them to surrender and rejoin the larger group. Kenobi successfully defended against the two Sith brothers, ultimately causing Maul and Opress to escape.
Following the incident on Florrum, Death Watch, a dissident group from Mandalore, found the severely wounded Maul and Opress. Together, they established the Shadow Collective, a criminal syndicate, thus achieving the objective that Maul and Opress had originally aimed for on Florrum.
