Falls
The sacred blue waterfall in Madeira is well-hidden, and a tightly kept secret among the townsfolk. They rightly fear the world's instant attention to their protected paradise of legendary healing, and restorative powers. The fall's source lies deep in a nearby granite mountain's core, that too is an unknown location, among vast underground lakes, grotto lagoons, and pitch black caves with timeless streams. The rich luminescent glow even the elders cannot explain, or their ancestors, only gratefully in awe. If you ask nicely and are in need, they'll kindly bring you a cask, so you may feel your soul healed.
