After you succeed in passing the guards outside the fountain area, you may continue your course downhill. Because the fountain is in a crater, there is a deep drop downward, followed by an attack of magical beasts, such as dragons and minotaurs. Best be quick footed for this course, but there is a message on the ground. You must complete the riddle before you may move to tier three. Otherwise, the magic will hold you back, even if you run as powerfully as your legs may allow.
