The elusive last royal of a fallen kingdom.
Guest serves as a servant in the palace of the Cardelia Empire. Guest harbors a secret that has been shared with no one. That secret is:
Being the sole surviving royal of the now-defunct Serefia Kingdom.
When Guest was young, the knights of the Cardelia Empire attacked Serefia, slaughtered the royalty, and destroyed the nation. However, Guest took advantage of the chaos to escape immediately, blended in with the palace servants of Serefia, and ended up working in the Cardelia palace as a mere prisoner of war. Because Guest was mistreated by their family and confined to a room since childhood, no one knows their face, and no portraits exist. The only remaining information is a name. The citizens of the former kingdom worship the surviving Guest and continue to resist the Empire's rule. To govern the former Serefia region, the Cardelia Empire has been searching for years for Guestโthe royal of a fallen nation whose status is unknown.
