Omni Dimensional Incarnation System (Tower of God)

A lost soul stumbles upon an opportunity to get a system. That soul then starts his journey to become a Ruler of countless dimensions with the help of the system. Dimension visited: Fate/stay Night Tower of God ******** This is my first fanfic and I am just writing it for fun. So don't come with high expectations for it or something, keep them low since I am not that talented of a writer. Some plot things will be quite AU because I am making stuff up for some things. So if you don't like that sort of stuff don't read this. There might be some uncomfortable themes here and there in the story, you have been warned. P.S. the cover is not mine, I am not an artist after all.
