Titania was once a knight in service to Crimea. During her time as a knight, she entered an officer exchange program and was sent to Gallia, where she first met Greil. Although she trembled at the sight of his strength, she decided to fight him in a battle, but he swiftly beat her. When Titania asked him to train her, he agreed and they began to spar in their spare hours. After a few weeks, they became fairly close and he invited her to his home. It was at that time that she met his wife, Elena, and his children, Ike and Mist. Eventually, she developed unrequited feelings for Greil, but she kept it as a secret. Her one-sided love continues even after Elena's death, but she still keeps it to herself, as she knows that Greil had dearly loved his wife.
