Okay, so, Phin is like, the kid of a superpowerful god, and when they were captured by Randall Strike, he figured that out and sent a message to his boss, the third son(or the CEO). Some of the sons of the Devil intercepted the message. They were having a conversation about it and the person on the left overheard them. He's the youngest son of the devil. he kinda needs a name. he's also living sulfur. if that makes sense. anyway, he wants to prove himself, so he goes and takes Phin from Randall strike by using magic. He accidentally transports them to an outer region of Hell and they have to either find the necessary ingredients to get to Hell's palace or they have to walk. So, they start walking, while everyone else is looking for Phin, cause they are powerful.
