Ashen Keeper

After the flame finally died down, a world has come to an end. But, what happens to the keeper of the flame? This is a marvel x dark souls x dc(unlikely) fanfic. I have always wanted a priestess like character to arrive in some superhero world so bear with it. This is my first book. Also, if anyone of you know how to change it into the fanfic part, please inform me in the comments. Notice: No romance. All characters belong to their respective owners and the cover image is from the internet uploaded by an account called Zerochan. I uploaded another exact same story with the title "The Ashen Keeper" in the fanfics place. Please don't read this anymore as I will be uploading there from now on. It is the same exact cover.
