Mysa Nal is the younger daughter of the High Seer of Naltor, she was born "blind" in terms she can't see into the future, like her fellow Naltorians who have precognition powers. After her mother died, her older sister Nura promised to protect her. But, Mysa refused the offer and left for Sorcerer's World, there she studied the magical arts. She becoming an accomplished sorceress. Mysa showed a remarkable aptitude for magic. She easily excelled in her studies — much to the chagrin of the envious Mordru. Originally, she had red hair, but as she trained in magic, her hair and skin became chalk white and her eyes bright red.
White Witch (currently named Black Witch) was created in 1966 by writer Jim Shooter and artist Curt Swan. Though introduced to the Legion back in the Silver Age, she did not actually become a Legionnaire until 1982, during the Great Darkness Saga. She became the tenth and final female member to join the Legion in original continuity, and the Legion's 31st member overall.
Original Continuity: New Earth
Mysa first appeared as the Hag, an evil witch. She was a member of the villainous Prince Evillo's Devil's Dozen. When the Legion Of Super-Heroes fought Evillo, two mysterious "new" members ( Star Boy and Dream Girl) in disguise as they cast a spell that restored her to her true form. It was later revealed that this transformation had been done by the villainous wizard Mordru. Mysa reappeared as White Witch with fellow sorcerers, managed to summon the spirit of Darkseid's ancient enemy Izaya, who in turn brought about Darkseid's defeat. She and joined the Legion of Super-Heroes and become friend's with fellow Legionnaire Blok.
The reboot Mysa was no longer Dream Girl's sister from Naltor, but rather, the daughter of Mordru. The only survivor of a group of sorcerers who imprisoned Mordru, she spent a century preparing for his return, including planting the seeds for Zoe Saugin's powers and manipulating much of the girl's life to make her an ally against Mordru's next rise. After Mordru rose again, Mysa (who resembled the pre-boot Hag at this point) was reverted to the age at which she first defeated him and helped the Legion imprison him once more. Mysa settled on Sorcerer's World and fell in love with Dragonmage. Mysa was also a physical vessel for the disembodied soul of Amethyst, one of the Lords of Order who is currently active in the present day DC Universe. It can be assumed that this Mysa was wiped out when Earth-247 was destroyed in the Infinite Crisis.
The Earth-Prime version of White Witch has appeared as a member of Mekt Ranzz's Wanderers. Her home planet is listed as "unknown." Her current whereabouts are unknown after Mekt's arrest.

This Mysa storyline picked up before Five Years Later, she is a slave of Mordu on Sorcerer's World. She is freed by fellow Legionnaires and helped back to Earth. Once there she helped Brainiac to call in other Legionnaires from different realities to fight against Superboy-Prime and his Legion of Super-Villains. When Prime killed Kinetix, Mordru gained all of her magical powers (and all magic of Earth-247 with in her). Mordru then gravely injured fellow Legionnaire Blok, who was trying to protected Mysa. Enraged she used her most powerful spell "Aufero Magus Infusco" which caused all Mordu magical powers and his physical form to be absorbed into Mysa, causing her to transform into the Black Witch.
