Ezekiel recognized early in life that he didn't want to follow in his parent's footsteps and spend the rest of his days as a mere farmer. No, his eyes are set on a grander stage, a place where tales of monster hunters, mighty generals, and benevolent heroes hold court — A world of Magic and mysteries.One day, the opportunity he had been waiting for arrives. Without a second thought, Ezekiel throws himself headfirst into the adventure. However, not everything turns out to be as magical as he had dreamt it to be...THIS IS A SLOW BURN FANTASY PROGRESSION LITRPG STORY:Even though you are not going to see blue boxes from chapter one, I guarantee you that this IS a LitRPG story. This is, however, NOT a pure “game world”! Instead, I have tried to integrate the interface elements of a LitRPG into a world with a very thought-out magic & power system, which will be explored over the course of the first book.This world doesn't work like a game, where you can put '5 points in strength' and the body somehow changes magically into a stronger version of itself. It might take a couple of chapters for the world and magic to start to make sense, but I feel like a power system built on solid principles is a lot more rewarding in the long run (...and more IMMERSIVE!).
