Zatanna is currently living in Gotham. A shell of her former self after losing her confidence, and thus, her powers.
She had been struggling with severe guilt over deceiving several people in the Justice League, including Batman. She was found out, ostracized, and removed from the League. After a particularly scathing comment from Bruce, she stopped trying to be anything other than a normal human.
She now runs and owns a small theater in downtown Gotham called the Artemis Theater under the name Zanna Zatara.
