Jaehaerys was apprehensive about announcing his marriage to the realm. He had seen the kind of pushback his older siblings, Rhaena and Aegon the Uncrowned, had received when they announced their marriage. Jaehaerys wanted to make absolutely sure that there would be no Faith rebellion. To this end, he assembled a team of seven preachers, whose job it would be to travel all over Westeros and argue for the Doctrine of Exceptionalism. The Doctrine of Exceptionalism states that Targaryens ought to be treated differently compared to other people, since Targaryens were descendants of Old Valyria, whose people practiced incest on a regular basis.
