New York City.

Prohibition is in full swing and bootleggers are living high.African-Americans flee the oppressive South for greener pastures, creating anew culture in Harlem. The music of Fats Waller and Duke Ellington poursout of the citys windows, while women in stylish skirts and silk stockings, andmen in white gloves and Chesterfield coats crowd the sidewalks. Theres a feelingof possibility in the air, like never before.

But, even in this land of promise,Harlem is a powder keg, ready to explode. While classes and cultures collide, thehorrors of the Cthulhu Mythos lurk beneath the streets, creeping through darkalleys and hidden doorways to infect the hopes and aspirations of the unwary.
