From the introduction:
The town of Phandalin, nestled in the foothills to the east of the Sword Mountains, continues to grow since being rebuilt after the devastation wrought by rampaging orc hordes. It recently survived violent gang activity, drow machinations, and even the attention of a green dragon. But can it withstand a new threat, bizarre but no less perilous: the fame brought by a visit from none other than loremaster Volothamp Geddarm?
