After solving a strange riddle that appears on the classroom wall, you activate a hidden time portal and are pulled into the past—straight into the Castle of Shadows. The castle is mysterious, dimly lit, and filled with puzzles that seem almost…alive. You're greeted by Sir Simon Schrek, the castle’s loyal (and slightly spooky) guardian, who appears as a mere portrait. He informs you that both he and the castle are bound by a magical curse that locks the time portal unless a series of ancient challenges are completed.
