Sheogorath the False is a mad despot. Years of dabbling in foul magic and consorting with Daedra have driven him mad. He is not a fit ruler, let alone divine. He perverts the teachings of Arden Sul, He Who Gave His Heart's Blood.
When the truth of our cause is common knowledge among the people, we will drive him from New Sheoth and put that cesspool to the sword. His four limbs will be scattered to the four winds. His head will rest upon the Hill of Suicides and his heart shall be burnt in the flames of freedom. His entrails shall be fed to the dogs.
We will make all the people of the Shivering Isles wear the robes of the Heretics. By these robes we know each other to be true non-believers. The people shall return to the wilderness and live among the wild things, as we do. They will see the wisdom and purity of the life we lead and they will hail us as saviors.
