The Infamous Drunken Harpy is up for sale at DriveThruRPG. This is statted up for Old School (Swords & Wizardy, Labyrinth Lord, Original D&D) and for 5th Edition D&D. Includes Maps, descriptions and NPCs, including some special guests of the Harpy (seems like they are there Every Tuesday). It can be purchased at DriveThruRPG
if you know someone who games, please send them the link as well. The setting information is pretty much generic and it would be easy to use with any game system with a minimal amount of work.
