Synopsis:

"Grounded Forever"

(Jun. 1987, 22 pages)

In a Danger Room sequence, the New Mutants are all killed by the Marauders. Magneto restricts them to the estate for defying his orders (iss. 46) and putting themselves in jeopardy.

Illyana battles back S'ym's revolt in Limbo, but her Darkchilde nature becomes stronger.

Shan reminds Magneto that her brother and sister are still missing (since NM #46)

Magneto offers to help Illyana defeat S'ym and reassures her that if he could stop being an evil mutant, then she can overcome the demons in her soul.
