Mana (マナ) is a mysterious power that can vanquish the undead. Originally, Mana referred to the idea of a holy power passed down through the seafaring people of the North Sea and Boltic Sea. It is said among Normans, however, that long ago, chosen warriors who could wield Mana developed ways to incorporate it into their combat techniques.
To this day, the Normans regard Mana as a formless power that imbues swords with victory and ships with safe passage.
