Events in Darjarpor are pretty much all over bar the shouting. With the leaders in custody, most of the cultists are rounded up. Their disassembled catapult is found and their flammable mixtures dumped into the swamp. Interrogation of Mela and eventually Gil reveals that they have been bankrolled by Duke Generaux of Pennisia. The mysterious cloaked man was his agent and was not caught in the roundup - he seems to have been too much of a professional.
Given that Section Unicorn has no Pennisian speakers, the task of punishing the Duke is left to Section Wolf. The Unicorns get to spend the fall and winter in the capital being exhaustively tutored in various languages to extend their range. Sasha applies herself particularly to Miskian. Gaius deepens his appreciation of Elvish poetry, particularly the "Lament of the Vermin" - 1200 pages of irritation at the human overrun of the continent thousands of years ago. The others are less focussed.
In the larger world, the first practical applications of the golden orb arcanology are demonstrated when amplifiers for force spells are created and used to provide sufficient force to propel airships without sails. The Emperor remarries, his previous wife having died of a wasting disease some years before. And the Pirate Duke of Moncanto is rumored to have taken to the sea again, after so many years without setting foot on a boat.
