Epic of the Apostate: Heretic

A lonely soul will embark on a journey to its destiny. What path will be chosen and whether he will be able to survive in an unknown place? Will luck smile at the hero or will he be destroyed? Find out here.
The story is at the beginning the backstory of my heroic spirit, during the course of the plot the hero gets to the wars for the Holy Grail. (There will be a harem, but I don't want to put this tag yet, all tags will be updated during the story)
