Kylie Vance was an officer in the commission of the Systems Commonwealths High Guard, serving on the flagship Andromeda Ascendant. She served on the vessel as a security officer, and was in charge of a small squad. During the Battle of Hephaistos, just as the Nietzscheans were betraying the Commonwealth, she and her squad were patrolling the interior of the Andromeda for intruders, when Tyr Anasazi appeared, because of Seamus Harper's Tesseracting machine from the future. They were sucked into the future, and saw Tyr, and opened fire. While pursuing Tyr, Major Vance saw Captain Hunt. He, also from her future, told her to hold off similarly timewarped Kalderans from pursuing them. She obeyed, and she was eventually sent back to her own time. ("Ouroboros")
