It's from MCDM's Strongholds and followers if you want to run the module. The map has three layers.

The second level was added with a change to the story line if you want to add it in. The castle now was abandoned after a spirit attacked and killed the noble family and chased the rest of the household out. The spirit is the court wizard who was researching a cure for a disease impacting the nobles child Clemency and discovered too much and became an Alipp.
