Recap continued:
Charlie also offered to teach the kitsune's lover, a changeling queen of a smaller hive than that of queen Crysalis, how to lock her dreams from unwanted intrusion, but that would have to wait until she slept. They arrive at the ruins of the Castle of the Two Sisters, where the other changelings of her hive hide in the shadows. A siren disguised as a flightless Pegasus (Moonlit Serenade) loses control of her siren instincts begins feeding off a pink zebra Pegasus, who seems to be put into a trance, so Omen, a strange shadow creature gets them out of public with portals to another dimension and ends up bringing them to the castle as well. Omen uses her portals again to get Princess Luna to help, but she ends up confronting Queen Allure, the changeling queen. Queen Allure wouldn't reveal herself, so Luna ricocheted a blast of magic off the Everwood stick that the kitsune was still impaled with. Because Everwood disrupts changeling magic, the blast disrupted her telepathic link, hurting her and her son. Luna brought a doctor, who was also a changeling but of another hive, to treat their injuries and those of the kitsune. He joined their telepathic link as part of their treatment. Charlie also became linked to them because his Everwood magic was involved in the incident. The spider slayers sleep while Luna uses a piece of Everwood she purchased from them to make a necklace to turn Serenade into an actual Pegasus, with the ability to fly. Charlie meets with the demon mare and Briar in their dreams, and they make the final arrangements for a body for Charlie and eyes for Briar, which Charlie chooses a changeling body from a questionable source, though is too naive to know he should question it. Charlie then goes to Queen Allure's dream and teaches her to seal her dreams. Immediately after the lesson as Charlie is trying to leave, The Forgotten One takes Charlie and uses him to gain new powers and keep himself hidden when he would eventually go to the waking world. Allure listens as she is told to seal the door and save herself. Allure awakes with no memory of the dream, due to the demon clawing at her dream before she could seal it. During the night, The Forgotten One took a few victims, making the world forget them and making them basically incorporeal. As Seamore and some of the others plant the seeds from the Everwood in a clearing, Spider people attack them and both the kitsune and her lover at the castle. Eventually a truce is formed and some of them eventually end up in Ponyville fighting the creature, separating it from Charlie. They kill the creature, but not without some major damages in Ponyville, including a collapsed balcony and a demolished clock tower. The victims of the demon are returned, including those that were taken before it was sealed away.
P.S. I know I mixed up some stuff, but I don't feel like correcting the chronology.
