Synopsis
In 1492 DR, a group of adventurers are hired by the Avowed to aid a grippli village in the Cloak Wood, a major supplier of giant crab meat for Candlekeep. The adventurers discover that the grippli are caught in the crossfire between two groups of yuan-ti: a goodly faction worshiping a deity they call the Scaled Mother, and a group of Sseth-worshipers hunting them down.
