The Core Rulebook is the single unified resource for both players and Gloom Master. The book includes an expansion bestiary, with narrative backgrounds, stat blocks, and combat inspiration for over 30 iconic Gloomhaven enemies. The book shares new immersive lore, which has been newly collected and written by a handful of RPG industry veterans and Cephalofair team. Featuring lore and story with history, characters and events about the city of Gloomhaven and the surrounding regions. The book also showcases detailed cartography, with work by the renown Francesca Baerald, exploring 8 regions in and surrounding Gloomhaven, with highly detailed maps, setting and location entries and interactable cities, towns and geographies. Included in the core rulebook is an adventure for any new or experienced mercenaries, taking you on a 20-hour module which will take place over multiple sessions. 

While the Gloomhaven board game offers a highly tuned tactical combat experience, this new role playing game inserts that combat experience into a new RPG framework that allows for Gloom Masters to tell their own stories and build their own adventures, while allowing players to fully realize and embody their characters. The slick combat is there, but it does not have to be the focus. We are encouraging players to interact with the world of Gloomhaven however they want in all new ways.
