Elizabeth is the deuteragonist of BioShock Infinite, Burial at Sea - Episode 1, and the protagonist of Burial at Sea - Episode 2. She is a 19-year-old[11] woman who has been imprisoned in the flying city of Columbia since she was an infant and who Booker DeWitt is sent to retrieve and bring to New York City unharmed. She is guarded by Songbird, a monstrous, winged creature who was both her keeper and only friend during childhood. However, she began to hate him as she grew up, seeing him as a warden prohibiting her freedom. Elizabeth has the power to manipulate Tears that exist in the fabric of time.[12] When Booker frees her from her tower on Monument Island, Father Zachary Hale Comstock, his party of Founders, and Songbird are all determined to recapture her at any cost, while the Vox Populi, the other faction, are determined to kill her.
