Rise of Voidwalker

After a hero gives up his humanity to save his world he hearts grows dark and he turns into the biggest threat in his universe

(Heyy so I'm here to explain how this came to be. So originally Voidwalker the main character of this story was intended to be the final villain of the first story I begun to write but as I was working on his character I feel in love him and instead of finishing the original story I decided to tell voidwalker's story first, I still intend on telling the original story but as of now just think of this as a precursor to it, the intro to the new universe I'm trying to build)
