Breel was a male Ferengi.
Quark and Rom knew Breel when they were young. On one occasion, Rom incurred debts to Breel, who demanded that the debt be settled by Rom agreeing to "sell" his right hand to him. Keldar talked to Breel's father to get Rom out of the deal, but Breel's father refused. Quark took it upon himself to right the wrong by buying Breel's debts to others and forcing Breel to "return" the legal rights to Rom's hand. Years later, Colonel Mitra, the insane commander of the Gallitep camp, learned of the incident after torturing Quark and Rom and threatened to cut off Rom's right hand and send it to their Moogie Ishka.
