Many years ago, the crime-fighting magician Zatara confronted an old enemy, King Inferno, on the slopes of a mountain near Sindella's home, a hidden city in northern Turkey. The battle ended in a massive rock slide that severely injured Zatara. Sindella rescued Zatara and nursed him back to health.
After a time, Sindella and Zatara would marry and have a daughter. Sindella seemingly died after giving birth to Zatanna, but actually decided to return to her people in Turkey.
Some time after Zatanna's eighteenth birthday, the evil elemental Allura placed a curse on Zatara that ensured both his and his daughter's death should he ever see her again.  To save Zatanna, Zatara left Earth-One on a quest across the various dimensions to find a good counterpart of Allura that would counter the spell.
Zatanna became a stage magician like her father, wearing a copy of her father's outfit. Soon, she became a super-heroine and decided to begin a quest for her father. Asking the aid of various super-heroes, Zatanna eventually traveled to the other-dimensional world of Kharma, where a good Allura forced the evil one to release the curse put upon Zatara.
Meanwhile, in the city of the Homo Magi, the Hidden Ones started to tap Sindella's "medulla jewel," a part of her brain which emanated a special type of energy. Zatanna also possessed a "medulla jewel," and Sindella feared the Hidden Ones would soon start feeding off her. Sindella established a psychic link with her daughter, which also resulted in trans- forming Zatanna's costume into a replicate of Sindella's. Shortly thereafter, Zatanna joined the original Justice League of America. She and her father were finally reunited with Sindella in the Homo Magi's hidden city. However, Sindella sacrificed her life against the Hidden Ones.
After her mother's death, Zatanna decided a clean break was needed, and for the first time, she wore a costume of her own devising that resembled neither her father's nor her mother's. It was during this time that she began a romance with fellow Justice Leaguer the Flash, which ended in friendship shortly thereafter.
