The Cinematics of Breathing Thoughts

Years ago, a mistake was made. The one who made the mistake learned from it, and all was thought to be peaceful. Well, until the result of the mistake decided to destroy the one that made it, and the whole world aling with it.Now, two teens, a pre-teen, and a toddler have been flung into the past in an attempt to save reality, by preventing the mistake from happening in the first place. And all they need to do is find the one who made the mistake, while trying to keep their identities hidden from their parents, keeping the toddler safe inside a bunker filled with things that are highly dangerous, and that's not even mentioning the fact that they're up against one of the most stubborn beings to ever exist!
