After the war, Constance and Mercedes traveled together to the school of sorcery in Fhirdiad. There, they immersed themselves in magical research and, with the help of their friends and all the school's resources, made one astounding discovery after another. Their considerable achievements led to the revitalization of both House Nuvelle and House Martritz. The pair grew increasingly close over the years so that, as time wore on, they became less like friends and more like family. It is said that, years later, each began to speak of the other as if she were a dear sister.
