Born on the planet of Tirimus Cortana Gravois was sister to Jedi Master Truth Gravois, she however did not seem at the time to have sufficient force sensitive abilities and unlike her brother was not asked to join the Tirimonian Knights. Cortana instead joined the Tirimonian Navy, eventually becoming one of the finest pilots on the planet. It was said that she could fly a ship close enough to the nearest sun Stella-Prime to catch a sun tan in five seconds without allowing the stars gravity to pull her space shuttle into its burning core.
