The Fury or Berserk state is potentially an ancient form of free magic passed down through the Royal Bloodline that manifests in an uncontrollable rage. This state allows the user potential to accomplish great feats of strength, will, and over all power. Due to the increase of power during the Berserk state the user becomes far more capable of controlling powerful free magic creatures, this power can often aid a Berserk into becoming a free magic sorcerer. Many Berserks over the years turned to books such as "The Fury Within" to help them in controlling the uncontrollable rage inside of them. Although it is most persistent in the Royal Bloodline it also occasionally occurs in the Bloodline of the Abhorsens. Known Berserks are Touchstone, Kerrigor, Jaciel, Clariel and Gullaine.
