According to Plato's Symposium, Greek myths used to say that there were three different genders; male, female, and a combination of the two. Fearing the power they possessed, Zeus, God of the sky, cut the combinations apart into separate male and female counterparts. These counterparts were then forced to live with a hopeless longing for their other half, stuck in a seemingly endless search for their soul mate. There is a shred hope, however, for these separated beings, for each of them has a special pattern etched like a scar into the palm of their hand, signifying the place where their skin was cut away from the others. Each pattern differs, much like a person's fingerprints. In this world where two halves must work to become one, Desirae is faced with the task of finding her own other half, balancing trials of her heart and tribulations of her mind on her epic journey of other self-discovery.
