New Mutants #25 kicks off the Game of Thrones-ish four-issue story arc 'The Labors of Magik,' in which the Sorcerer Supreme and the rightful queen of Limbo, Illyana Rasputina, receives a challenge for her throne by none other than Marvel's Goblin Queen.
New Mutants #25 is written by Vita Ayala and illustrated by Rod Reis, along with a backup story written by Ayala and drawn by Jan Duursema with colors by Ruth Redmond. Marvel describes it as a flashback story set during Illyana's time in limbo with revelations that impact the main present-day story and will run throughout the entire arc.
