"I entrusted it to my faithful retainer, Jonas Escalus, the only servant who didn't betray me when Tulak Hord moved against me. He swore he and his heirs would keep it safe until the time that my heir would return to claim it."
―Aloysius Kallig[src]

The Escalus line was a Human bloodline that included Jonas Escalus, a servant of the ancient Sith Lord Aloysius Kallig. Before his death, Kallig entrusted his lightsaber to Jonas, who swore that his family would protect the weapon until Kallig's heir reclaimed it. However, centuries later, Mila Escalus's father lost the weapon gambling.
