A roleplaying game of dark whimsy and fairy-tale horror set beneath the city's streets. Beneath the bustling metropolis lies the wondrous UnderCity, where the lost and discarded dwell alongside the echoes of myth and nightmares. Built on fairy tales and forgotten dreams, it is a place of chaos, magic, and peril where anything is possible. But a darkness is rising, threatening both the world Below and the world Above. Seeking to make their mark in this strange realm are the Thread Runners. Armed with rusted blades and magic words, these rogues, mercenaries, and heroes may be all that stand against the coming danger. UnderCity is an urban fantasy roleplaying game set in a secret world that lies between the cracks and beneath the shadows of our own. Swift and simple character creation and an easy-to-learn dice pool system places the emphasis on unique personalities and the momentum of the plot. Take on the mantles of charming Buskers, gutter-born Gourmands, Sewer Sirens, and other strange denizens of the Below. Navigate the byways of the UnderCity, battle monsters in haunted subway tunnels, forge trade routes through clinging Weblands – whatever it takes to keep the two worlds safe.
