This is a cool new building that has been converted from KoH to AoK and serves as a lighthouse, a building which AoK lacks. However, the building doesn't really match any building set, making it difficult to fit into the game.
The quality is very good, as evidenced by the screenshot, but as I mentioned earlier the graphic doesn't really fit with any building set. There is no readme, only a .exe file which is the installer of the graphic. In the future, the author should provide the .slp files as another forumer mentioned so as to allow modders to use it as they see fit.
Potentially a fine addition to somebody's mod or game, I recommend the download.
