Fiona

 Fiona is a ghost from Ghost Story Island. As the island progresses, it is revealed that the central plot of the island revolves around her past.

History
Fiona had a love named Valiant, and was a friend of Henry Flatbottom, the Magistrate. Henry Flatbottom, on the other hand, was in love with Fiona and gave her an engagement ring to try and woo her. Fiona, however, was not impressed and threw the ring into the town fountain. On the day when she was supposed to leave Hemlock Harbor with Valiant aboard the Unicorn (a ship), Flatbottom refused to let her leave and hired a prisoner to forge a letter to Valiant, saying it was from Fiona and telling him to leave "without me". He departed with a broken heart and died when the ship crashed upon sharp rocks. Fiona was heartbroken and died years after.

Role In Ghost Story Island
Most people know her as the Woman in the Window. After obtaining the violin and playing it, she appears in the window and beckons you closer. You climb up the cliff and go inside the cellar, from there you navigate to the top of the house, you find a telescope, you look in it, and when you close it she mysteriously appears behind you. She claims to not be a ghost and tells you to go to the Gingerbread House and tell the baker, Jane that she sent you. You go to the Gingerbread House, and tell the baker. The baker then gives you gadgets, which you later utilize to hunt down the other ghosts. After you discover the story of Flatbottom and Valiant, the Cemetery Specter appears and you reveal him to be the Magistrate. The Magistrate claims he is truly sorry for those he had wronged. Fiona then appears before you as a ghost, along with the other ghosts and accepts his apology. She and Valiant are then reunited and the two rest forever in peace along with the other ghosts.
