In the Undercity, the Mysticons meet Zarya's old childhood friend, Kitty Boon, who is a sky pirate. Things get suspicious as said pirates begin raiding all around Drake City. Fed up with her friends' disbelief and doubts, Zarya leaves and is shocked to discover that her old friends have been after the Mysticons all along, so that they can claim the ancient, all-powerful Dragon Disk for their employer for gold.
Zarya tries to stop Kitty, who leaves with the Disk in her hands. Because of this, Princess Arkayna considers Zarya to be a "disgrace to the Mysticons" and furiously leaves the Valley of Lost Ships on Izzie, with Piper and Emerald, leaving a tearful Zarya alone. In Dreadbane's hideout, Kitty hands him the Dragon Disk, which he triumphantly presents to his army of undead skeletons.
