The pamphlet appears on the streets of Westcrown suddenly, on the afternoon of the second day of the convention, in sufficient volume that its publication was obviously a coordinated effort. It is not full of strident denouncements; the Queen has forbidden those, and the denouncement of an archduke would surely attract attention sufficient to locate and silence its author.
In fact, apart from the title, the entire pamphlet is just a reproduction of a page from The Great and Ancient Houses of the Empire, vol. XI, with citation given, which is surely entirely legal to post on a street corner. It shows the descendants of Ferran Blanxart, Archduke of Cheliax (now called "the Heartlands") in the early 40th century from the ascension of Aroden; a highlighted line is traced down to the son of the daughter of his second son, showing the present Archduke's claim to the title. His name is given as he wrote it then, as it still appears in ancient genealogies:
ALFONSO ANTONINUS I———E THRUNE i Blanxart
3951–3989, Conde d'Egorian 3974–3989
(His third given name is conveniently obscured by an ink smudge.)
