Born on the outskirts of the Empire, on a desolate Outer Rim planet, Hiljo was inducted into the Sith Order just days after his birth, as soon as his Force-sensitivity could be confirmed. Spending the first sixteen years of his life as a part of a Sith pack, Hiljo eventually gained entrance to the prestigious Sith Academy on Korriban. Once there, the Sith warrior trained for a further nine years before being taken as an apprentice, although this relationship did not last long.
