Yeah ,this was something that I did to give you guys a little sneak peek.
So yeah this shows what the story will be and I know I basically used the Dracula Untold trailer as the basis of the trailer here, but to be honest since Jaune is Dracula now I figure that I might as well use the trailer, it was awesome.
Hopefully you guys enjoy this sneak peek and I hope I'll have the first chapter ready soon as I can
