Duplicitous Form Execration

The Duplicitous Form Execration is the calligraphy style said by the Immaculate Order to have been devised by the Anathema for their own dark purposes.

An Anathema might take the body of your loved one, might know all they knew and speak as they spoke, might have eyes that glimmer with all the familiar emotions of the one you knew... but they are gone, it is deception, only the evil of the Anathema remains. So too is the writing of the Anathema deceptive in every way, for the symbols they put down have great power to deceive, to seem as if they are of a different form entirely, even one of the Three Perfected Styles of Calligraphy set out in the Immaculate Texts. The faithful must not believe this illusion, must not accept those forms as true, must cast such texts into the purifying flames of Hesiesh or hand them over to the Order to be sealed away as were the Anathema themselves in the Jade Prison by the hand of Danaa'd. For, if the illusions of the Anathema's calligraphy disguise the very shapes of their letters, what terrible lies and curses must hide unseen amongst their content, waiting to be unleashed upon Creation?
