1- The fall of the Monsters

My version for the backstory of the Fellswap( or 'Swapfell') brothers and their gaster. Gaster was known as the Captian of the Royal Gaurd. He was a ruthless killing machine during the war with his wife fighting alongside him. His wife is killed during the last fight signifying the monsters defeat. Now, Gaster raises his son's to take his place when the time is right.
