From publisher blurb:
Attack in Wicker Woods is a Fifth Edition adventure designed and optimized for four players of 2nd level. This adventure works best set in a deep wood or thicket.
Background
A clan of nasty grosslins (chaotic evil, chicken-like humanoids) have settled in a dungeon ruin located deep in the Wicker Woods. These creatures only take pleasure in sacrifices made to their manufactured deities: Grakknovar and Plekknovar that are in reality a mating pair of cockatrices. The grosslins make a habit of burning humanoid victims alive in a grand ritual in front of their deities' 'avatars’. While exciting to the grosslins, this act never truly satisfies their chaotic blood lust. Anyone caught by these vile creatures does not last very long...
