The party is returning to the Keep with their prisoners from the Mill when they're attacked by another group of raiders. The party defeats them easily, thanks to Alaomena casting Bless. Upon handing the prisoners over to the Governor, the party learns that the raiders are looking for something in town but are happy to loot while they look. The raiders belong to some dragon cult, but the prisoners don't know more than that.
During this time, while the party is up on the parapet, the blue dragon Lennithon swoops down overhead, and the party spots a quick peek at Frulam Mondath, in her purple robes below in town.
As the night raid winds down, the party hears a shouted challenge from outside the Keep. Outside the main gate, Langdedrosa Cyanwrath, a large half-blue dragon, is holding the family of one of the Keep guards hostage. In exchange for a one-on-one fight, Langdedrosa will release the hostages. The party manages to convince him to release the children when Talon agrees to fight him. In an epic, close fight, Talon manages to take down Langdedrosa, who is not killed but carried off by his men.
The sergeant, whose family was held hostage, offers to let the party long rest at his home, while the Governor gives the party a healing kit and 2 healing potions in thanks.
After the long rest, the party meets an injured monk, Nesim Waladra, who asks the group to find his missing master, Leosin Erlanthar. Leosin is said to have been researching the dragon cult that attacked the town. The Governor has also asked that the party find the raider's camp.
