From the journal
During his stay in Skellige Geralt learned of something called the Path of Warriors. This was an obstacle-strewn route locals believed each self-respecting warrior must travel. Geralt knew if he managed to traverse the infamously-difficult Path he would earn respect and recognition throughout the isles.
The witcher overcame all the obstacles along the Path and made it to the end. From then on, even the proudest Skellige warriors would treat him with respect.
