Hart, softback Greyhawk supplement for AD&D 2nd/2.5th edition
The ‘Castles’ boxed set included three 48 page softback books, posters, maps and cardboard 3D pieces covering a castle in each of the three main AD&D settings (Forgotten Realms, Dragonlance and Greyhawk).
The NEAR MINT condition copy is the 48 page softback book describing Hart (ONLY), a castle in the Greyhawk setting, plus a large map of the castle and a poster of the cover art. It includes new rules and statistics for Battlesystem.
The VERY GOOD condition copy is as above, but is only the book (i.e. no map or poster).
