The Ice Falls

The Ice Falls is a legendary location in Naiko. According to legend, the Ice Falls is a sacred Fairy site located in another legendary location, the Forest of Life, which is supposedly near the Mountain of Hope and the Mountain of Bravery. It is possible that these locations could be the Forest of Destiny and Mountains of Destiny as referenced in the legend of The Land of Destiny.
Although the exact location of the Ice Falls is not specified in the legends, the mention of it being a Fairy-specific ritual site would place it in the western area of The Eastern Continent where the Fairy Plains are located.
Below is a transcription of the description of the legend of the Ice Falls from an ancient source.

Legend

The Ice Falls is a sacred place where fairies get sacred water for rituals. For very sacred rituals, some fairies bathe in the pool. The Ice Falls lies in the Forest of Life, which has many sacred animals and plants. It falls off the edge of the Enchanted Cavern, which has many mystical carvings on its walls and ceilings. The point where the Mountain of Hope (left) and the Mountain of Bravery (right) meet is called the Sunset Valley. Every evening at twilight the sun is right between the two mountains and the animals perform the sunset ritual. Also, in the morning, the sunrise ritual is performed. At noon, the sun shines straight down through the falls and the midday ritual is performed.
