In a landside, where two rivers flow into a lake, many unexplainable events took place which were recorded for the past centuries. It’s assumed that they all originate from the water that seems to have special properties. Some say it enhances healing by an incredible amount.
Ever since, the place has become of great importance for pilgrimage and eventually the gigantic Cathedral of the blessed waters was built. A big system of sewers runs under the cathedral which lets the water flow into collecting vessels.
