"Did you think that I was going to leave and stay gone?"
Nathaniel eyed every person in the room. They had won the day but the fight had only begun. They stayed in their perfect worlds. While they were celebrating he was planning his revenge.
They rendered him helpless when they all came together to stand against him. It was only fair that he returns the favor.
What better way to make them all helpless than to make them right their precious legacies? Without their heirs, their future and lineage were threatened. It would take a real monster to kill their child.
So he turned their children into his protective shield. For anyone to reach him, they have to fight through their loved ones first. And the worst part was that he had mastered death. All of his summonses can only die by his hands, so if they died fighting, they would return almost immediately.
