History
In the world of Mutopia, Professor X killed himself to stop Cassandra Nova from using Cerebra to erase all mutantkind from existence, the psychic feedback it caused knocked Jean Grey (who was in mental contact with Xavier at that time) into a coma and cased her inside a Phoenix Egg. Magneto, who guided mutantkind after Xavier's death, placed the Egg inside a machine in the basement of the Atom Institute,[1] and had been using it to pump the student body with MGH and to inhibit the powers of the old X-Men, filling them with doubt.[2] In addition to that, Magneto was hoping to use Quentin Quire and Esme Cuckoo as psychic parents to prematurely hatch the Phoenix Egg, and release what was left of the Phoenix Force from within it, so he could control its power.[1]
