At the beginning of the game, it shows the Hero's dream: s/he sees a girl in white running away from an old man. The girl trips and is caught by the man as his hand covers her face and the man sees a large crystal. The girl notices the crystal, and the man begins laughing. Then the crystal shines and the hero wakes up. That day it is his/her 16th birthday and his/her coming-of-age ceremony, in which the Hero is required to set out in the Forest and find the crystal.
When the hero reaches a clearing in the forest, Sherlotta appears, floating on the Crystal, and she tells the Hero that s/he has passed the test. Sherlotta gives the hero a Crystal. Soon after, even before the village has time to celebrate, a girl in the village named Eryll falls ill to a disease known as "crystal sickness". The Hero must leave the village to find a cure for Eryll, and begin his/her adventure.
