It is said that every ten thousand years, the ancient ruins of a temple city created eons ago by unknown civilization appears for but a brief moment at the first entrance of daylight, hovering over the body of water among the Three Falls.
How it hovers, why it is there, and where it goes for the remainder of this time is a mystery; although, it is said by some that the ruins are not ruins but actually an inter-dimensional gateway to this civilization. Perhaps if one could find his way on to the ruins in time before it takes its leave, he or she could truly know.
