Stark Commercial Combine

The Stark Commercial Combine was a group of Outer Rim pirates and mercenaries organized, lead by, and named after Iaco Stark. During the bacta shortage of 44 BBY, the Combine became heroes to the poor people of the Outer Rim when they began raiding bacta shipments and redirecting them to the planets that otherwise could not afford them.

However, it was still piracy, and combined with the fact that the bacta 'shortage' did not even exist, it was enough to cause the Stark Hyperspace War against the Galactic Republic. Although the war ended witht he Combine's defeat and the death or capture of many of its members, a good deal escaped to continue their work as mercenaries, pirates, smugglers, and terrorists.

Stark himself, and presumably the formal remains of the Combine, later joined the Commerce Guild.
