 A TLDR of Horde of the Dragon Queen, Episode 1, Greenus and Flames. Traveling to Greenus, you see smoke arising from the town. A blue dragon emerges and seems to be attacking it. You rush into the town and bump into some townsfolk. They're being attacked by cobalt and cultists. You rescue the townsfolk and take them to a place known as the Keep. From here you meet the governor of the town and he sends you on missions all night to rescue more people and gather more information. You learn the cultists belong to a group known as the Cult of the Dragon. They've been gathering loot for a nest of dragon eggs nearby. The raid ends with a blue half-dragon named Cyanrath who approaches the Keep with some people as prisoners. He challenges someone to singles combat, whoops their ass, and lets the prisoners go. Time to go find the Raiders camp.
