The Call of Cthulhu Setting
Call of Cthulhu is deeply rooted in the themes and entities of H.P. Lovecraft's fiction. This includes a pantheon of ancient, incomprehensibly powerful cosmic entities such as Cthulhu, Nyarlathotep, and Azathoth. These beings exist beyond human understanding and are indifferent or hostile to humanity.
The classic setting for Call of Cthulhu is the 1920s, often called the "Roaring Twenties." This era's mix of post-World War I optimism, burgeoning technology, and social change provides a rich backdrop for tales of horror and mystery. However, the game can be adapted to other time periods as well.
The game's adventures can span the globe, taking players from the bustling streets of New York City to the remote corners of the Egyptian deserts, or they can be localized in small, claustrophobic settings like a secluded New England town.
A key element of Call of Cthulhu is the psychological impact of encountering the otherworldly and the unknown. Characters are at risk of physical harm and losing their sanity upon encountering eldritch horrors or forbidden knowledge.
The game often revolves around investigation, with players taking on the roles of detectives, scholars, journalists, and other archetypes who are drawn into mysterious and supernatural occurrences. Uncovering clues, deciphering ancient texts, and solving puzzles are common elements.
Characters in Call of Cthulhu are typically ordinary humans who are far more vulnerable than typical heroes of fantasy RPGs. The emphasis is on their fragility in the face of the incomprehensible and unknown, making survival and sanity preservation key aspects of gameplay.
The game is supported by an extensive lore based on Lovecraft's stories and expanded by subsequent authors. This includes detailed descriptions of ancient gods, alien races, forbidden books, and mysterious cults.
Call of Cthulhu emphasizes atmosphere, mood, and storytelling. The horror is often psychological and creeping, built through suspense, foreboding, and the gradual revelation of the horrific.
