The Dales are a dangerous land dominated by the forest of Cormanthor, bordered on the west by the Desertsmouth Mountain range, the east by the sea of stars and the south by Sembia, a duchy who have all but closed off trade with their neighbouring regions.
At the foot of the Derertsmouth; Daggerdale calls for aid as people go missing and livestock is taken by monstrous humanoids from the surrounding region. It has never been a safe place to live, but the free folk are nearly ready to give up holding the frontier town that guards the west border of the dales.
Four adventurers seek out the source of the trouble under contract from Elminster the Sage. But as they it is often want to do, something evil lurks in the dark.
