The freehold embarked on a rescue mission. After neutralizing four Hob guards (in front of a now very drugged-up mortal), we snuck into the Lord of Black Iron's Camp. Tommy and Sarah snuck into the "kennel" where we believed (thanks to Prague's crazy dream) Edmond to be imprisoned while everyone else created a distraction (which mostly involved the Summer knights being totally badass).
Sarah turned out to have been working for the Lord of Black Iron the whole time (albeit unwillingly, as she apparently has to obey whoever possesses her heart) and the rest of the rescue party was soon dragged into the kennel as well, to speak with the Lord of Black Iron via the mirrors that lined the room. He offered to make a trade for Edmond--two other changelings (or one equally entertaining one) for the Summer King.
Prague immediately jumped up and ran off to go find Mallory. Edmond revealed that he had been captured because he had broken a oath sworn on his keeper--an oath to never fall in love. Mallory came to the camp willingly (?) and agreed to take Edmond's place if Autumn would still have a monarch. This prompted Tommy to regale everyone within earshot (the entire camp) with terrifying tales of Autumn's wraith. At which point Mallory's eyes went weird and everything went crazy.
Some amount of time later, we all woke up covered in mud, surrounded by many dead/similarly unconscious Hobs and changelings. Tommy had the Autumn crown on his head and took Sarah's heart. The heroes of the freehold limped back to Tucson.
Did I miss anything?
