Once apon a time there was a Jack Frost that had a land of his own and he govern it on his own. Everything was ok but it was not because the Jack Frost 6 brothers and their raptors came and send him into a watery tome that led deep into the underground's of a place called Mementos. The 6 brother then broke into war and laid waste to the Jack Forst's land. Legend says in Mementos the Jack Frost evolved into a Black Frost and lost his way to the shadows then he became something worse titled Black Frost the Cold Hearted.

The Shadows sound like they have nice lives.
