Life on the streets is hard. The homeless are invisible. New York City has almost one hundred thousand homeless. Each night they sleep in the city’s parks and subway system, invisible to the population who passes them every day. What better victims could one ask for? Players take on the roles of New York City’s street homeless as they come together to solve the mystery of something that is stalking and killing the members of their community. When a relative newcomer to the streets turns up dead in a dumpster, her death is chalked up to just another example of street violence. The local homeless know better. Something is stalking them. Something no one has an explanation for. With nowhere else to turn, they must band together and save themselves before they become just another statistic. The Night Mother's Moon is a 1-2 night scenario for modern Call of Cthulhu set in Manhattan, suitable for 2-4 investigators.
