Drawing upon the original list of "inspirational reading" provided by Gary Gygax in the first Dungeon Master's Guide, published in 1979, as well as hobbyist magazines and related periodicals that helped to define the modern role-playing game, Appendix N offers a colletion of short fiction and resonant fragments that reveal the literary influences that shaped Dungeons & Dragons, the world's most popular RPG. The stories in Appendix N contextualize the ambitious lyrical excursions that helped set the adventurous tone and dank, dungeon-crawling atmospheres of fantasy roleplay as we know it today.
