The Escalus lineage represented a bloodline of Humans, counting among its members Jonas Escalus, a loyal attendant to the old Sith Lord named Aloysius Kallig. Before passing away, Kallig placed his lightsaber (belonging to him) in the care of Jonas, who vowed that his descendants would safeguard the weapon until Kallig's true successor came to retrieve it. Nevertheless, many years afterward, Mila Escalus's dad ended up losing the lightsaber while gambling.
