After Lorna had fully recovered from the injuries inflicted by Sabretooth, Havok met with her to explain his recent behavior. Turned out that he was working undercover the whole time, not wanting to waste the chance of investigating the Dark Beast’s operation from within. Lorna was able to understand, though not forgive, him for betraying and even trying to kill her. Whatever they once had together, Lorna felt that it was gone and she ended their years-long relationship. [X-Factor (1st series) #148]
Still, she agreed to become part of the revamped X-Factor team, consisting of herself, Havok, Multiple Man, Shard, Fixx and Greystone. The new team were to act independent from the 
government and to become a well-respected superheroes that would not only deal with mutant issues but all threats. However, during their first meeting, Greystone developed a severe case of temporal insanity and started to construct a time machine to return to his native timeline. Despite the dangers involved, Havok tried to reason with the boy and left Lorna in charge of the team, should anything happen to him. Indeed, the malfunctioning device blew up, seemingly killing Alex Summers (though actually his mind was transported to another reality). [X-Factor (1st series) #149] Apparently, Polaris didn’t feel capable of holding X-Factor together after that and the team disbanded.Weeks later, Nightcrawler encountered a rather hectic Lorna in a church and she confided in him that she felt she was being followed and that she was sure Alex was still alive. [X-Men (2nd series) #93-94] A group of Skrulls, working with Apocalypse, were indeed shadowing her and broke into her apartment to retrieve the headgear from Havok’s original costume. Lorna then learned that she was one of the fabled Twelve, a team of mutants destined to usher in a new golden age for mutantkind. Polaris journeyed with the X-Men to Egypt to battle Apocalypse, but it turned out that the legend of the Twelve was fake. Apocalypse himself had started the rumor of the future leaders, trying to lure these particular twelve mutants together, as he wanted to combine their energies to gain omnipotential power.
Polaris and Magneto provided the opposing magnetic poles, Storm, Sunfire and Iceman stood for the extreme forces of nature, Cyclops, Phoenix and Cable represented the unison of family, while Xavier was the power of the mind, and Bishop and Mikhail Rasputin being the control over time and space. The vast energies bundled in the form of the Living Monolith, through whom Apocalypse tapped into the power. The headgear that the Skrulls had stolen was now worn by the Monolith to help him regulate the bundled energies. However, the Twelve broke free and, during the encounter, Magneto discovered that he could use Lorna to tap into the Earth’s magnetic field with incredible force, effectively hiding his current reduced-power state. [X-Men (2nd series) #97]
After Apocalypse was defeated, Lorna returned to Genosha with Magneto to supply him with power and help him keep order. She believed she was doing it for the greater good, not being able to influence Magneto's rule of the island nation, but also knowing that she enjoyed the education in her powers that she was receiving. In the end, Magneto launched a full-scale assault on Carrion Cove, the last city opposing his rule, in order to gain access to technology left behind by the Sugar Man - technology that would restore his full abilities.
Knowing that, with his powers fully active again, he would no longer need her, Polaris attempted to stop him, but was defeated by Magneto and forced to leave the country with the Avengers. She later snuck back in with Quicksilver, to help oppose Magneto’s tyrannical rule from the underground. [Magneto: Dark Seduction #1-4]
Before long, Quicksilver was discovered and forced to leave the country again, but Lorna managed to keep a low profile and helped to transport refugees to supportive African nations, like Wakanda. Polaris even stayed after the X-Men ended Magneto’s plans of starting World War III with an army of mutants. [X-Men (2nd series) #113, Uncanny X-Men (1st series) #393] 
The master of magnetism having received a near fatal injury, Lorna could roam around the island more freely and took the chance to clear up something that had been nagging her for long. Although it had been said that she wasn’t Magneto’s daughter, some doubts had remained - after all, they did have the same powers and her parents had died under mysterious circumstances. As Magneto was doing a lot of medical testing to find a cure for his severed spine, it was rather easy for Lorna to steal a blood sample from a lab, with which she departed to have an independent, blind genetic test done by someone without any possible hidden agendas. While she thought she had prepared herself for every eventuality, Lorna was still shocked when Magneto was confirmed as her genetic father. [Uncanny X-Men (1st series) #430-431]
Shock turned to anger when Polaris researched the FAA reports of her mother’s plan crash, only to find that there had been an oddity - the investigators had found the wreckage to be highly magnetized - Magneto’s doing? Furious, Lorna returned to Genosha and landed in front of Magneto’s headquarters to confront her father. However, Magneto had somehow learned of her discovery and spread word on Genosha that she was his true daughter; 
the people in the market place greeted her as a celebrity. Before she could even think about how to deal with this situation, Genosha was attacked by a new breed of Sentinels - wilder and harder to fight than ever before. It all happened too fast and there were too many of mutant-killing robots, slaughtering the Genoshan people one by one. Lorna knew many of them on a personal basis but she couldn’t do anything to help. Sixteen million people died that day and, while she was one of the handful survivors, protected inside a magnetic bubble, Polaris didn’t come out of the ordeal unscathed. Hearing the Sentinels repeatedly declaring the Genoshan people as non-human entities before executing them, human judgment passed on mutants, something in her mind snapped and she could only think one thing: Magneto’s way had been right all along! [Uncanny X-Men (1st series) #431]
Several weeks after the attack, X-Men and X-Corp members re-visited Genosha to check on the island nation’s condition and to offer help to the few survivors and other mutants that, in the meantime, had come to Genosha. From them, the X-Men learned of residual magnetic energy fields appearing all over the place and them being attracted to a green-haired woman. 
Checking out this phenomena, the X-Men found the deranged Lorna, naked and confused, acting as a living conductor to some sort of magnetic black box, in which Magneto had recorded everyone’s thoughts in the instant Genosha died. To prevent her conscious- ness from bursting open, the X-Men had to break Lorna free from the magnetic field energies. She still managed to single out Magneto’s voice of all of them and boosted the signal so that everyone could hear his last words. Lorna then helped to turn the deactivated Sentinels into a giant monument of Magneto, so that everyone would remember. [New X-Men (1st series) #132] The fact that she kept calling out to him as her "daddy" the X-Men seemed to write off to her confused state.
