The path of the hero is a path built on sacrifice, and for Paul Jackson, one life sacrificed should have been enough. But when the world needed him most, another one was granted. A chance to go back to the beginning. To the spawning of the world dungeons. The coming of the system. Before the calamity. To undo what had been done. To prepare. To guide those who needed guiding, and most of all….To save his son.
