As you follow Flóki deeper into the forest, you come upon a clearing bathed in golden sunlight. The map he carries seems to glow with an ethereal light, guiding you towards a towering oak tree at the center of the glade. Birds sing melodious tunes from the branches above, their feathers shimmering like rainbows in the dappled light. Suddenly, a rumble shakes the ground beneath your feet, and roots begin to emerge from the earth, coiling around the ancient tree. A booming voice echoes through the woods, 'Only those pure of heart may claim the treasure hidden within this tree.' Flóki looks up at you with wide eyes, his tiny form quivering with excitement. What will you do?
