The Trees Are Awake

From publisher blurb: The heroes are approached by a mysterious stranger who offers them a princely sum in exchange for invading the magical laboratory below Holdwood Manor, a local property of the Green Order of the Forest, and destroying the results of the wizards’ magical research. To succeed, the heroes must successfully infiltrate the Manor’s grounds, find the entrance to the laboratory, and then deal with what’s inside. Three to five characters of third level are optimal for this one-off adventure. This is a 5th Edition D&D adventure set in The World of Avlis campaign setting, but may be used as a drop-in for any fantasy medieval campaign setting.
