She is a determined but soft-spoken woman who only reveals her powers when they are absolutely needed.  Due to her unique life history, Amanda is very accepting and open minded when confronted with strange people and beings.

Margali raised the children in a small Bavarian circus, where she pretended to be a simple fortune teller.  While Kurt worked on becoming a circus performer, Margali trained Jimaine in magic.  The brooding Stefan eventually left the circus to make his own way in life.

The small circus was taken over by a rich Texas millionaire, who ordered Kurt to be placed in the freak sideshow.  The anguished Kurt quit the circus and headed toward Winzeldorf, West Germany, where Stefan lived.  There Kurt discovered that Stefan had gone mad and killed two children.

Two days after leaving the circus, Kurt tracked Stefan down and tried to capture him.  During the fight, Kurt accidentally broke Stefan's back, killing him.  Civilians discovered Kurt with Stefan's body, and because of Kurt's demonic appearance, they assumed that he had killed the two children.  Kurt was saved from the mob by the psionic powers of Professor X, who asked Kurt to join his new team of X-Men.  Kurt agreed and went to America with Professor X.

Margali blamed Kurt for Stefan's death.  Jimaine, who had long ago fallen in love with Kurt, followed him to America and watched over him secretly.  She became the airline stewardess Amanda Sefton, and arranged to accidentally meet Kurt.  She mystically disguised herself so he would not recognize her, and they began dating each other regularly.

Margali eventually took her revenge on Kurt by exiling him to a pocket dimension she had created.  The dimension resembled hell as depicted in Dante's Inferno.  Amanda, pretending to be Margali, kidnapped Kurt's fellow X-Men and Doctor Strange.  Amanda then sent them to the same dimension that Margali had sent Kurt, hoping that they would be able to help Kurt.  Kurt finally confronted Margali in this pocket universe and convinced her of his innocence.  Amanda then revealed her true identity to Kurt.

Later, Amanda Sefton heard a rumor that Dr. Strange needed a new apprentice, because Clea had left him.  She went to Strange and asked to become his new apprentice, as did every crackpot in the world who heard about the rumor.  Strange arranged for all the petitioners to meet at one spot, where he told them that he currently had no wish to take on an apprentice.

Amanda's mother, Margali Szardos, appeared and attacked Strange.  Margali was angered that Strange had refused to take on her daughter as an apprentice.  Strange cast a spell to force himself and Margali into the astral plane.  Margali warped the spell so that all the would-be apprentices were also forced into the astral plane with them.

Strange and Margali battled with all their mystic forces.  Strange soon realized that Margali's powers came from her wand.  Strange tricked Margali and took the wand from her.

Margali immediately regained her true mortal form, that of an old woman.  She explained to Strange that the wand was an evil entity that took over its owner's mind.  Margali revealed that the wand had hoped to gain control over Strange.  Upon returning everyone to the physical plane, Strange destroyed the wand.

Amanda continued her relationship with Kurt as well her career as an airline stewardess, while she ignored her magical studies.  When the mystical Dire Wraiths invaded Forge's skyscraper headquarters in Dallas, Amanda helped drive the Wraiths off.  Amanda and Kurt kept seeing each other for a long time, but they finally parted as friends.

Recently, Amanda joined a group of former X-Men and X-Men allies in protecting Muir Island from an invasion by Donald Pierce's Reavers.  They were warned of the attack by Freedom Force, who also joined in the defense of the island.  During the battle, Stonewall of Freedom Force was killed.  Unknown to Amanda and the other members of the Muir Island X-Men, they were soon under the mental influence of Legion.

Meanwhile, the multiple personalities of Legion were actually under the control of the mysterious Shadow King.  The Shadow King was the first mutant villain that Professor X encountered, years before Xavier formed the original X-Men team.  They fought a telepathic battle in the astral plane, which apparently ended in the Shadow King's death.

In actuality, the Shadow King had become a being of mental energy, able to possess the bodies of others.  It has recently been revealed that the Shadow King is also the true power behind the Hellfire Club.

After months of being controlled by the Shadow King, Amanda and the inhabitants of Muir Island were freed by the combined efforts of Professor X, the X-Men, and X-Factor.  The Shadow King was apparently killed, and much of Muir Island was destroyed in the battle.
