Amanda Nix was an influential aristocrat who strove for knowledge all her life. Together with other researchers, the girl studied ancient manuscripts and treatises in libraries throughout Erikuria. From one diary, she learned about the white blood of a thunder bat, which allowed her to heal wounds and cure any disease. Amanda decided to check it out.

It turned out that white blood really does have healing properties, but for this it is necessary to conduct magical rituals. The girl mastered them and began to secretly conduct rituals, healing her comrades. Rumors of healing spread, the number of Amanda Nix's followers grew, so the girl created a secret order "White Blood", and she herself became its Magister.

But healing alone was not enough, Magister Nix wanted more. Therefore, she remade the rituals, making the white blood stronger. After one of these rituals, Amanda and some of her followers turned into monsters.

The girl began to be pursued by former members of the order, who had become hunters. To avoid being found, Amanda hid in the caves of Erikuria. There she devoured thunder bats in the hope that this would help her regain her human form.
