After ignoring Thimbletack's warning, Simon is abducted by a group of invisible goblins. Thimbletack guides Jared to a seeing stone device created by his great-uncle which gives the ability to see faeries, called the Sight. Mallory and Jared go searching for him, narrowly escaping capture, and find the goblin camp. While rescuing Simon, the hobgoblin Hogsqueal convinces them to help him escape in exchange for his help in retrieving Simon. Hogsqueal spits in their eyes, giving them the Sight permanently. After rescuing Simon, they flee and lead the goblins to the troll where they meet their end. They rescue the rest of the goblin's victims and take an injured griffin back to their house
