Palace of the Silver Princess

Palace of the Silver Princess is an adventure module originally published by TSR in 1980 for the Dungeons & Dragons Basic Set. It was recalled on the same day it was released, then rewritten and re-released some months later. The original version, with an orange cover, was written by Jean Wells. When the orange version was recalled (and most copies destroyed), the module was rewritten by Tom Moldvay and released with a green cover in 1981. Writing credit on the second version was given to both Moldvay and Wells, although there was very little of Wells' original content in Moldvay's version. Palace of the Silver Princess contains a single D&D adventure laid out in a format suitable for a single gaming session. The module includes game maps on the unattached outside cover.
