Xargressians were a long lived species who lived around the core of Corellia. They were part of ancient Corellian legend, which said they were immortal hell beasts. In reality Xargressians lived for close to ten thousand years. The oldest recorded Xargressian was twelve thousand seven hundred and six years old. Many scientists theorise that the Xargressians were related, albeit distantly, to the unknown species that such famous Jedi as Yoda belonged to; another long-lived and secluded species.
