Great Power, Comes Many Responsibilities

During the Civil War between Iron Man and Captain America, Peter's and Cain's children attempted to fix the mess that the war had caused to their families. So they broke into the Sanctum Santorum and tried to use a mind wiping spell to erase everyone's memories of Peter unmasking himself, but as they did it, Mephisto appeared and was very angry with the children for getting in the way of his plans, so he sent them away to different worlds in the hopes that it'll keep them away.

But doing so will cost him greatly as one day, the children will return, stronger and more powerful than ever before as they return with the strength and knowledge to help their families and all they care about as they face many villains and false heroes in the process as they start to bring their families back together.
