Hoard of the Dragon Queen features a cult whose leaders wear purple robes, but even though the adventure presents that as an important character detail, I can’t figure out from the text which characters are actually robe-wearing leaders.
The overview of the cult in the adventure preface mentions that leaders wear the robes but the cult otherwise has no clear hierarchy. A sidebar in Episode 2 mentions the robes again, but this time also describes a hierarchy of cultists, apparently contradicting the first description. The “Prisoners” mission in Episode 1 suggests that the PCs might encounter a robe-wearing cultist other than the named NPC leading the attack, but not how or where. All of this contradictory information has left me very confused as to whether any of the many unnamed cultists also wear purple robes, and if so who.
The part that confuses me most is the “Prisoners” mission. Its exact wording gives me the impression that there’s more than one purple robe in Greenest, and the players may have encountered one:
If the characters haven’t run into any cult leaders yet, Nighthill takes them onto the parapet and points out what he means. This is an ideal time for everyone to catch a glimpse of [the enemy leader].
Because there’s no clear mention of the robes anywhere else in Greenest, it’s not clear how or where the players would’ve seen one. The enemy leader doesn’t appear in any of the other missions or random encounters, and there’s not enough information given about her to guess where else she might be. All this makes me wonder if there’s more robes than the one explicitly mentioned – perhaps the highest-ranking cultist in the “Sanctuary” mission?
