Book excerpt: An anthology investigating the influences behind Dungeons & Dragons, the most popular modern role-playing game. 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. Featuring tales by Poul Anderson, Frank Brunner, Ramsey Campbell, Lin Carter, Lord Dunsany, Robert E. Howard, Tanith Lee, Fritz Leiber, H. P. Lovecraft, David Madison, Michael Moorcock, C. L. Moore, Fred Saberhagen, Clark Ashton Smith, Margaret St. Clair, Jack Vance, and Manly Wade Wellman.
