Alongside his nurse Abby, Will embarks on a journey outside Zeno, forming alliances and facing challenges. Legion's plans unravel, leading Will to the Palace of Wish, where he sacrifices his wish for the freedom of a broken girl, Kata.

As he faces eternal torment in a city square, a chaotic event unfolds, sending him deep underground. Cursed with immortality, Will discovers a glimmer of hope and emerges into the desert, finally free.
