Other folk thought the Rage was simple bloodlust, a berserk savagery that neither knew nor cared what its target was, and so it was when it struck without warning. But when a Trapani gave himself to it knowingly, it was as cold as it was hot, as rational as it was lethal. To embrace the Rage was to embrace a splendor, a glory, a denial of all restraint but not of reason. It was pure, elemental purpose, unencumbered by compassion or horror or pity, yet it was far more than mere frenzy.
