The female Traveler receives an urgent request from Fischl, the eccentric investigator of the Adventurers' Guild, who has discovered an ancient ruin hidden in the forest outskirts of Mondstadt. What was once a quiet, mysterious place has become a site of strange disturbances—whispers in the wind, shifting shadows, and unsettling movements that make it seem as though the ruin itself is alive. Local villagers have reported hearing voices at night and claim that the ruin has become cursed, causing the forest around it to slowly wither.

Determined to uncover the truth, Fischl enlists the help of the Traveler. Together with Fischl’s trusty raven, Oz, they venture deep into the heart of the ruin. The shadows grow thicker as they explore, each step forward revealing more about the malevolent force that haunts the area. Fischl believes the curse may be tied to an ancient being, one that has been sealed away within the ruin for centuries, but it is slowly regaining strength.

As the Traveler and Fischl push forward, they uncover a dark secret—this isn’t just an ancient curse, but the manifestation of a powerful spirit seeking to return to the world. With every corner they turn, the ruin seems to shift, playing tricks on their minds. The deeper they go, the more Fischl and the Traveler must rely on their bond and their wits to survive.

To stop the shadow from escaping and wreaking havoc on Mondstadt, they must face its terrifying form in a final, desperate battle. With Fischl’s sharp intellect and the Traveler’s elemental power, they uncover the key to breaking the curse—but not without cost. Once the darkness is sealed away, the ruin slowly begins to fade back into silence, leaving the Traveler and Fischl to reflect on the mysteries of the unseen world that lie just beneath the surface.
