Due to a rebellion, Aurelia and Helena Aurelian were separated, with only a Golden Hairpin left as a token of identity. Later, Helena Aurelian was found by a villager, Alan Potter, who named her Elara Potter and raised her. Many years later, Aurelia has purged the traitors and secured her position as The Empress Regent, and decides to search for the long-lost Helena Aurelian.
