A vow on their own blood and flesh. A magic spell that has been passed down in every Allard generations' veins since ancient times. Known as the 'Bloody Oath' with the royal family. The vow that was cast on the heart and a manipulative one to the point it brainwashed the mind of an Allard to only serve the royal family with unending, unbending loyalty until their death, and earning that oath proved the authority of obtaining a loyal slave in a monarchy system. A monster who would kill countless people and even be ready to die at any time if it for the sake of imperialism. That was the fate which all of the members of house Allard should obey.
