Adventures in Middle-Earth: Erebor Adventures - Rules of Play says:
Erebor contains six ready-to-play adventures you can play separately or as connected parts of a conspiracy that will unfold over the course of several years. The adventures take place in the areas described in the Lonely Mountain Region Guide supplement – a useful companion to this volume.
Visit the Kingdom of Bard the Dragonslayer, see the wondrous toy-market of Dale and the reconstructed Lake-town. Gain access to the halls of the King under the Mountain, as you side with Balin son of Fundin in his search to foil a conspiracy threatening to bring war to the North.
