Mar Barezz

Mar Barezz was an agent of ISB.

Shortly after the Battle of Yavin, Barezz discovered that Rebel agent Tiree was going to Bothan's Planet to recruit new members for the Rebel Alliance. He went to an abandoned mine there, Mesa 291, which was the staging point for Tiree. Barezz's forces managed to intercept Tiree and almost captured him and the recruits; however, in the end, the new Rebels defeated Barezz, crippling his forces, and rescued Tiree.

Barezz would continue an obsessive search for Tiree, usually working with his personal friend Ref Mawber, another ISB agent and the head of a network of spies in the criminal organizations of Questal.

Barezz also took part on the Battle of Picutorion, working alongside High Colonel Drost and Commodore Bevven. Barezz and the ISB suspected that two of the Imperial officers in the battle, Captain Ganig and Sergeant Stecker, were Alliance supporters. Thus, Barezz convinced both Drost and Bevven to "sacrifice" both of them during the battle, sending them to a certain death, instead of allowing them to live and defect.
