In Folklore, players assume the roles of two main characters, Ellen and Keats, who are drawn into a mystical and otherworldly realm known as the Netherworld. Each character has their own distinct storyline and abilities. Ellen can harness the power of spirits and capture them, using their abilities in combat and solving puzzles. Keats, on the other hand, is a journalist who uses his investigative skills to unravel the mysteries of the Netherworld.
