Anton finds the witch's cottage and the witch, Arina, who turns out to be level 1 or higher, but not Fuaran. Instead, all Anton finds is a book about the legend of Fuaran which is co-authored by Arina. The book explains how Fuaran discovered how to raise the power of an Other, and grant a human the powers of an Other. According to the book, the average magical temperature of the world was 97 degrees, while humans had a magical temperature of 97 or higher. Their warmth is fed into their surroundings, while the Others have a magical temperature under 97, and thus soak up the 'warmth' that surrounded them. The lower an Other's magical temperature, the more they soaked up. Seventh level Others had a magical temperature of about 90, while Others without Classification were in the 40s. The rarest type of other is one who had no magical temperature at all, a Zero Other, whose power was near limitless due to the fact they only absorbed magic. After a talk with Svetlana, Anton discovers Nadya is an absolute Zero Other.
