Hylo Visz's father, a droid designer of Mirialan descent (male), resided on Balmorra with his wife and daughter amidst the Great Galactic War that embroiled the Galactic Republic and the Sith Empire. During the Battle of Balmorra, the Empire's initial assault on the planet resulted in the Mirialan's death. Though his wife and daughter managed to escape, his wife perished soon after on Nar Shaddaa, leaving Hylo an orphan. His daughter would later achieve fame as a galaxy-famous smuggler. The day before his demise, his landspeeder malfunctioned, an incident that shaped Hylo's faith in the Invisible Law of the Universe.
