At dawn, Ethan Harper and Max reach a vast valley to face the Test of the Elements. Using clues from their journal, they solve four linked puzzles representing water, fire, air, and earth--carefully redirecting a stream, rotating metal discs, aligning wind channels, and balancing heavy stones. When all elements are in harmony, a hidden chest rises from the ground. Inside, they find a new journal and map, revealing further challenges ahead. The trial proves their growth in logic, teamwork, and observation.
