The once thriving world of Solum is divided into four lands, each connected to one of the four elements. Now the planet's core is shutting down, creating a huge crater and isolating these regions. Solum is dying. The hope for Solum lies in an ancient prophecy: the birth of four children will awaken the legendary elementals, saving the world. But, in a land of winged people, the long awaited chosen one is a girl without wings called Air. Only the Land of Air's elder, Echo, has faith in Air... and that's enough for her! The young chosen one sets out on an adventure to find the last Chosen One of the Land of Water and save her world.
