Prashian is an aristocratic lineage endowed with 500 years of life and special powers. Elan are "normal people" who live for 100 years. In this place where these two "peoples" coexist, a Litra Palia lives among them without knowing her own name. Following the orders of servants, she survives on the charity provided by the Prashian to the Elan. She is merely a "pet".
