Alice, a painter who has lived in a quiet town since childhood, is drawn to the abandoned castle on the town's outskirts. Legend has it that strange noises can be heard from the castle on full moon nights, convincing Alice that untold stories are hidden within its walls. While exploring the castle, Alice and her childhood friend Alex discover mysterious letters, ancient books, and other clues pointing to an old legend—the town was once shrouded in dark forces, and a brave knight and a wise woman sealed a powerful force within the castle. To unravel the mystery of the letters, find a way to break the seal, and save the town, Alice and Alex embark on a difficult adventure. With the help of an old scholar, they continuously search for clues, visiting temples, mines, and other locations to find three mysterious objects to counter the dark forces.
