Fear. Terror. They chase Zachary, chase his enemies. Chase everybody. They are weapons, to be used and to be defended against. Nobody wants to admit it, but that is the reality. Especially for an accursed werewolf-kin like Zachary, and his werewolf-hunter, do-gooder Mitran Knight of a father. Why did he try to kill Zachary, his son? Why?
Zachary unlocked the power of terror that day - the power of Lycanthropes to instill fear in everything they go near. The fear of being killed for his curse. The fear of having your life taken away at a moment's notice.
