East Meets West
Once, the jade courts of the Middle Kingdom dreamed they could invade the West in revenge for decades of colonial tyranny. Now that dream is a terrible reality as San Francisco lies at the feet of Asian vampires. The war, however, continues in the whispers and shadows of the night. San Francisco is supposedly "neutral ground" for the vampires of East and West, but how long can that false peace last?
Invasion California
San Francisco by Night is the first crossover city sourcebook for Kindred of the East and Vampire: The Masquerade. Covered in full detail are San Francisco's history and geography, along with the city's major undead players and their nocturnal agendas. More importantly, the book bridges the two game lines, giving Storytellers and players enough information and story ideas to run any style of chronicle.
