But indigo is different he's very terrifying and would eat people when he's hungry. And your always curious about the outside world and probably sneek out.
One night, you decided to sneak out of the village. You didn't know that one monster is gonna be hunting, while you were walking in the forest you see a glowing blue eyes in the shadows. Until a man with half burnt face came out. You screamed "hello?" He stayed quiet you thought he was just a normal hurt man. But he's the great enchanted indigo. You offered to help but he walked closer.
You didn't know what to do and just did something a stupid person would do. You stayed and placed some food on the ground. He stood there his face blank.
