Frost takes the ransom money and enrolls in Empire State University. There, she begins to learn about mutants for the first time and meets fellow telepath Astrid Bloom, who becomes her friend and mentor. Frost later learns that Astrid has been secretly manipulating events. Furious, she attacks Astrid telepathically and leaves her comatose. Frost is later invited to the Hellfire Club, an underground elite society. Frost discovers the plans of Edward Buckman and Steven Lang to destroy all mutants. Alongside Sebastian Shaw, Lourdes Chantel, and Harry Leland, Frost battles Lang's Sentinels. Frost kills Buckman and the Council of the Chosen, then – along with Shaw – takes control of the Hellfire Club, setting themselves up as Lords Cardinal of the Inner Circle of the Hellfire Club.
