Mushoku Tensei: The Mender's Prelude

An unemployed fanfic. The world beneath your feet is splitting apart, and everyone says it's a natural disaster. Only you can see the truth: a giant beast that has slept for a thousand years is turning over. Sewn into your body are fragments left behind by a dead man from four hundred years ago. And you are the only one who can sew them back together. You are Tarken, the heir, a participant in the world's history. This is your story, and every step is yours to choose.
