The history of the Master of Nyx

Amanda Nix was an influential aristocrat and had been striving for knowledge all her life. Together with other researchers, the girl studied ancient manuscripts and treatises in libraries throughout Ericuria. From one diary she learned about the white blood of the thunder bat, which allowed her to heal wounds and heal any disease. Amanda decided to check it out.
 
It turned out that white blood does have healing properties, but for this it is necessary to conduct magical rituals. The girl mastered them and began to secretly perform rituals, healing comrades. Rumors about healings spread, the number of followers of Amanda Nix grew, so the girl created the secret order "White Blood", and she became its master.
 
But healing alone was not enough, Magister Nyx wanted more. Therefore, she redid 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 became hunters. To avoid being found, Amanda disappeared into the caves of Ericuria. There she devours thunder bats in the hope that this way she will be able to return to human form.
