and entitled Little Keep on the Borderlands. In September 2010, the module was re-released for D&D 4th Edition by Wizards of the Coast for use in the weekly D&D Encounters sessions as Keep on the Borderlands: A Season of Serpents. Like the original, this revised module was designed for use with the contemporaneously released Dungeons & Dragons Fantasy Roleplaying Game boxed set for D&D Essentials, which is oriented towards the beginning player. This time, The Keep on the Borderlands is set in the D&D base world of the Nentir Vale, in an area known as the Chaos Scar. The module is "a multi-week adventure as a set of individual encounters, each of which is meant to be run as a single session lasting 1.5 to 2 hours. [...] 'Season of Serpents' is the longest Encounters season ever, with five chapters of four encounters each, resulting in 20 total sessions of play. Considerable effort is expended to differentiate the chapters and the overall play experience; thus, PCs adventure in broadly different areas during each chapter of play. Nonetheless, many GMs found the adventure too long—mainly because it made it hard to bring in new players late in the season, something that matters more in an organized play environment". A revised edition was released at D&D Expo in January 2012 under the title Caves of Chaos as playtest material for the upcoming 5th edition of D&D. Players had to sign a non-disclosure agreement before playing the adventure. In 2016, the Brazilian publisher Redbox Editora released a remake of The Keep on the Borderlands called O Forte das Terras Marginais for their own retro-clone system Old Dragon. The module was translated and adapted by Rafael Beltrame, chief editor of Old Dragon. In March 2017 Mike Mearls, Mike Carr, and Chris Doyle announced that Goodman Games had entered a partnership with Wizards of the Coast to publish a collector's edition of The Keep on the Borderland and In Search of the Unknown. In January 2018 Goodman Games announced that the hardback book would be 380 pages in length and contain digital scans of the originals, 5th edition conversions, additional new content, and "testimonials". The Goodman Games reprint entitled Into the Borderlands appeared in May 2018 as volume one of "Original Adventures Reincarnated". In video games Dungeons & Dragons Online released an adaptation of the Keep on the Borderlands adventures in 2019. References External links
