For Call of Cthulhu 1920's

In dim forgotten recesses of the world lurk mind-twisting horrors. Through the use of human agents, these horrors work to thwart humankind's destiny.

However, not all of these human agents are willing partners. Many times have the monsters resorted to subtlety and intrigue to further their ends, rather than gross displays of wanton destruction.

Andrew Keetling is one such unwilling agent. A successful Boston businessman, he has disappeared and is now held captive, in a mansion of madness.

MISKATONIC UNIVERSITY is a small, seemingly typical New England college nestled in the bosom of conservative Arkham, Massachusetts. A poor cousin to such hallowed institutions as Harvard, Brown, and Princeton (the term “Ivy League” won’t come into use until 1936), Miskatonic nonetheless offers coveted degrees in a wide variety of subjects and boasts high academic standards.

Devotees of the Cthulhu Mythos and long time players of Call of Cthulhu know the name well, and greet it with a mixture of fondness and dread. A small, quiet institution of higher learning, Miskatonic serves as the home of many of H. P. Lovecraft’s greatest protagonists, or as the staging ground for daring expeditions into the unknown.

Kenya provides a setting that can be both familiar and foreign. Settled by Great Britain in the 1900’s it is an English-speaking colony where all the trappings of home can be found in the capital of Nairobi. Beyond Nairobi’s limits, much of Kenya remains unexplored and virgin territory for investigations, and hidden horrors.

The first half of this book provides a civil, cultural, political, geographical, and Mythos tour of Kenya during the 1920’s and 1930’s, the remainder offers four longer adventures using this background.

LOS ANGELES IN THE 1920s was a fast-growing, fast-moving city that encompassed all that was great and all that was rotten in America. Racial, ethnic, and religious melting pots presaged what the whole country would become by the end of the century. L.A. nonetheless clung to a veneer of White Protestantism more in line with farm-belt states in the Midwest. The newly-rich built pleasure palaces in her hills and on her beaches, while recent immigrants and the descendants of the first humans who walked the land huddled together in filthy shantytowns. These resembled the most squalid parts of the undeveloped world. Philanthropists endowed the city with impressive monuments and dreams of a utopian society, while greedy businessmen and industrialists crushed the labor movement and embroiled themselves in scandals that rocked the nation. Celebrated movie stars worked and played before the eyes of the world, while rum-runners and racketeers plied their trade behind the scenes in the land of noir, hand-in-hand with crooked cops and two-faced politicians.

Eastern sophisticates dismissed the city as an abode of the frivolous and the nouveau riche, yet underneath it all coursed an energy at once vibrant and unwholesome. Los Angeles was a place where anyone could reinvent himself, and multitudes did — at a price. It was also a place where dark and blasphemous secrets infested every level of society, belying the carefree and enviable lifestyle broadcast to the world. For behind the glitz and glamour of Tinseltown, primordial, inhuman forces and their twisted minions worked to undermine the very foundations of sanity.

It is more than a metropolis, it is a living entity whose unique character and changeable nature shape its atmosphere, its institutions, and its leading citizens. It is an excellent location from which to launch campaigns focusing on the Orient, and it possesses abundant research resources and outré locales for scenarios within its extensive boundaries, including the largest, oldest American enclave of Chinese settlers, the world’s most famous haunted house, and two of the most infamous prisons ever erected.
