The rulebook not only contained rules for character creation (including Monster player characters), combat, and magic but also wargames rules for battles and sieges. The background was heavily influenced by medieval France and Christianity, with Knights (tournaments, courtly love, fiefs, political influence), a hierarchical priesthood who could perform miracles, and a large section on monsters that included the Infernal Court of demons. In addition to ideas taken from Arthurian myth, the first edition also incorporated elements of J. R. R. Tolkien including hobbits and balrogs. These references have disappeared in subsequent editions for reasons of copyright. Thus, "C&S" has less of a modern literary influence than "D&D", which was not only heavily influenced by Tolkien but also other major fantasy authors such as Robert E. Howard, Jack Vance, Fritz Leiber, L. Sprague de Camp and Michael Moorcock.
