Long ago, Prince Caelan Vaelros, beloved heir of the Moonshadow Kingdom, was chosen as Guardian of the Last Moonbeast, a sacred creature born once every thousand years.

Under a lunar eclipse, Caelan swore the Oath of the Hunt, vowing to protect the creature and never raise blade nor bloodlust against it.
