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 married and had a daughter. Sindella seemingly died, shortly after giving birth to Zatanna, during a car accident. However, the truth was that she was abducted by her people and taken back to their secret city.
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 in order to save her loved ones.

However, some elements of the character's Pre-Crisis history may have been altered or removed for Post-Crisis New Earth continuity, and should be considered apocryphal.
