One told us that at the Dungeons and Dragons “factory,” there was a witch’s hut in the forest nearby. Before each set was packaged for shipping they were all sent out to her, where she personally dedicated them to Satan.
There was a series of books some of us read, young adult fiction (can’t recall or find the title), where some of the characters played D&D, lost their minds due to the devil’s curse, and died in awful ways.
I played anyway, of course, just not with friends from school.
