From publisher blurb: Journey beneath a thriving metropolis on a quest for a secretive enclave of librarians. This is a 3 hour adventure of love and pain for 1st and 2nd level characters. A Nest of Librarians is a starting module to begin the second season of Rats in the Rain modules. It is a 5E module intended for low level characters. These modules are set in and around the Golden Kingdoms cities of Boodar and Pesht. During the season, creatures and classes from Rats in the Rain expansions will be found along with the introduction of Rat Packs. References to Rat Packs are not critical to the game and can be found in the League of Rats Rules. During this season, expect to see stories featuring ancient secrets and aberrations. A Nest of Librarians is a short dungeon crawl during which the party sets out to explore a forgotten oubliette and find an old collection of maps. To the Vulgorn, knowledge is not just power, it is life.
