There is a story in Yudia that has been passed down for generations. Somewhere in the vast land of Yudia, there exists something called a Salttree, which guides people who get lost in the desert. Those who see the tree are safely led by Fairies to a place where they could be helped by other people. The tree turns into a pile of salt the moment it is seen by the lost, leaving a small fruit behind. Perhaps the fruit is the heart of the desert, wanting good people to find their way to safety.
