NerdCast RPG: The Cthulhu Collection
NerdCast RPG is a series of actual-play productions created by Jovem Nerd, Brazil’s largest pop culture and entertainment media brand. Over the years, its campaigns have reached millions of listeners and expanded into novels, comics, and tabletop games, becoming one of the country’s most influential transmedia fantasy and roleplaying properties.
Set in an alternate version of Europe in 1926, The Enigma of the Hidden Sun is a gamebook written by Karen Soarele for NerdCast RPG: The Cthulhu Collection, a project derived from the acclaimed cosmic horror campaign created by Jovem Nerd, Azaghal, and fantasy author Leonel Caldela. Throughout the adventure, readers take on the role of investigators drawn into occult conspiracies, ancient artifacts, and eldritch threats inspired by the works of H. P. Lovecraft.
The map depicts the city of Oxford, one of the story’s principal starting locations. Drawing upon early twentieth-century cartographic references, the piece combines historical research with the investigative atmosphere characteristic of cosmic horror. The goal was to create a functional representation of the city that could serve both as a navigational aid for readers and as an extension of the book’s historical setting and immersive atmosphere.
