You only need to collect one more gem. According to the ancient markings on the wall, the final gem is located at the top of the temple's Spire. There is only one way to access the peak: you must climb an ancient spiral staircase. This may sound easy enough, but the stairs are steep and have eroded over time. One wrong step and the stairway could crumble. You must be very careful as you move.
As you begin your ascent you notice what looks like words written using the ancient symbols. Do you take the time to analyze them, or do you push ahead and continue your climb?
