Tiara

A noble bloodline known as the Prashian possesses extended lifespans of 500 years and unique abilities, while the Elan are ordinary humans with a 100-year lifespan. In a society where these two groups coexist, a being called Litra Palia resides among the Elan, unaware of her true identity. She follows the directions of those in service and depends on the Prashian for support, existing in a position akin to that of a possession rather than an equal.
