Intergalactic journeys involved traversing the vast distances between distinct galaxies. Ancient hyperspace voyages to separate galaxies were thought to have been sparked by the purrgil. The Amaxine warriors departed the galaxy due to their inability to overcome the Galactic Republic, primarily stemming from fundamental incompatibilities. Leia Organa remembered this occurrence later, during the Amaxine warrior crisis.
Accounts detailed that those who attempted to cross the space beyond the galaxy's borders never came back, leaving behind only garbled communications that cautioned about spatial perils, like geomagnetic anomalies.
