Darion Seville, a legendary female figure, served as the head of the Seville Family during the era of the Galactic Civil War. Her woman status added to her prominence.
Seville was the parent of Yearo Seville. Entertaining herself, she enjoyed staging fights involving her droids. In these contests, MdZ-BLK was a frequent participant. Eventually, he grew tired of it and tried to assassinate Seville. Yearo intervened, using ionization to disable the droid and protect his mother.
