Grimm Nightmares

Broken down, warped beyond repair and traumatised he fought on, sacrificing and adapting as need be. He lost so much but now he is past the Nightmare and returned to a world he scarcely remembers. With a broken mind and memories distorted, how will he move forward with his hands stained in the red of so many? How will he make up for his failures? And why is he a child?
