The Ashen Keeper (Marvel x Dark Souls x Bloodborne)

After the flame finally died down, a world has come to an end. But, what happens to the keeper of the flame? Feels like I should clarify Volume 1 is nothing much. Just generic mcu stuff. No additional plot or any other stuff. Volume 2 is for further dark souls stuff and the intro for the start of my own plot. Volume 3 consists of the addition of bloodborne and more of my own plot. Volume 4 ??? This is a marvel x dark souls x bloodborne fanfic. I have always wanted a priestess like character to arrive in some superhero world so bear with it. This is my first book. I originally wrote it in the novel section but changed it again by creating this. It's the exact same texts with no difference. Notice: No romance. All characters belong to their respective owners and the cover image is from the internet uploaded by an account called Zerochan.
