The Heretics believe that Sheogorath is just a mortal man pretending to be a Daedric Prince. They summon Hungers and have a wide range of Destruction spells. They will also use Dispel to remove any magic-based protection the hero may be maintaining.
Like Zealots, Heretics have special robes and if one wears both the robes and the hood the Heretics won't attack unless the Hero gets too close. Heretic bosses always know that the Hero is an imposter.
Upon speaking to a Heretic Warlord (if disposition has been increased high enough), a dialogue box with the phrase, "I HAVE NO GREETING" appears along with a tan box in the upper right hand corner of the screen.
