In a burst of battle madness, Aron Peacebringer shatters his restraints.
Ryastraad, also referred to as battle madness, was a condition of intense fury or berserk-like behavior experienced by individuals of the Calian species under particular circumstances. This state of ryastraad granted the person capabilities exceeding normal human limits. When Aron Peacebringer believed that Leia Organa had been slain by Imperials, he succumbed to battle madness, enabling him to snap the heavy metal chain that bound him.
