Edena was a talented alchemist, but she had one critical flaw. She had an extremely low blood purity of only three percent. It was practically the lowest value possible. Edena belonged to lower mudblood, which was the worst thing that could happen to a person.
Persons with such low blood purity were treated worse than slaves. The reason was that because their blood purity was less than 10%, many people didn't even want to consider them as members of their race.
It was possible to correct the blood purity percentage, and there were quite a few ways, but all of them were extremely expensive or very dangerous. Only one person with a blood purity of less than 10% out of a million had a chance at a decent future.
Edena was not only censured by society, but she had to endure such illnesses all the time. She knew that Wain had a vial of blood essence, and it was her ticket to safety.
