Life in the Taris Undercity was tough, infectious diseases and hungry predators were always a major concern for it's citizens, not to mention the swoop gangs that came down from the lower city. Darrious was a just a young boy when his parents were killed by a pack of hungry Rakghouls, Darrious himself would have died if it wasn't for the heroic efforts of Jedi Master Jaco Hargan. After consulting the council Jaco took young Darrious to the Jedi academy on Yavin IV.
