Parents were infected/killed by the Rustov, and forced his future mentor, Hovarth, to kill Skerren's now Rustov parents right in front of the young child. As a result of this, he has a hate for the Rustov that burns with an eternal flame. He knows his way with a sword, thanks to his mentor, and master swordsman, Hovarth's training. Previously despised Jack, because the Rustov killed/infected his parents, and Jack was infected with the Rustov parasite, and technically was a Rustov. But now he is so close to Jack, he is now like a brother to the infected boy.
