Hoard of the Dragon Queen - Dragons of Faerûn
Greenest is a town that lies along the Uldoon Trail in the Greenfields region of the Western Heartland/Sword Coast. Its chief livelihood comes from trade along this route, bringing gold to the town’s merchants and craftsfolk. Greenest is run by Governor Tarbaw Nighthill at the behest of the town’s inhabitants.
At the beginning of the adventure, the party finds the town of Greenest under siege by what they later determine to be the Cult of the Dragon under the leadership of Frulam Mondath and her underling Langdedrosa Cyanwrath. During the raid, the cult utilizes a blue dragon named Lennithon.
