Dornian Heresy

The Dornian Heresy is a non-cannon rebellion held by Rogal Dorn in the series "If the Emperor had a text-to-speech device". At the very end of the first podcast, the Custodes bring out some questions for a Q&A segment. One of viewers (under the persona of a planetary governor) asks the Emperor whether the correct day to dine upon tacos is Tuesday, or Thursday. He goes on to state that his planet is in a state of anarchy because of this, and that he hopes the Emperors word will put an end to the unruliness. In his infinite wisdom, the Emperor rules that the day to dine upon the taco is Friday, in order to celebrate the coming good times of the weekend. Rogal Dorn disagrees, stating that not only is the alliteration of "Taco Tuesday" vital, but also that the tacos should be consumed on the Tuesday so that the bog-standard imperial citizen is given some light in an otherwise cold, dark, week. This Argument continues for some time, ultimately causing huge civil wars on Terra and eventually spreading to the rest of the Imperium. This argument continues on in the next podcast, with Uriah of the last church as a guest speaker on the show. Uriah says that tacos should be consumed on the day of ones choosing, and not a pre-determined day. This vexes both the Emperor and Dorn, saying that the taco cannot consent to being eaten unless it is upon the day of the taco. It is yet to be seen what will happen to the Imperium at large because of this, but it will surely be on the scale of the Horus Heresy, if not far worse.
