Dismemberment of Osiris
The Setite ritually dismembers the captured leader of a group or organization, starting with the limbs and finishing with the penis. (The ritual works only on male victims.) At the conclusion of the ritual, the Setite drops the phallus into a tank full of fish. It only works if the fish devour the severed organ.
The organization headed by the victim suffers a serious calamity, as determined by the Storyteller. A corporation might lose half of its stock value overnight, a military unit could fall in battle, or a religious order might experience mass defections. The ritual takes six hours to complete.
