Both Foul and Deep
This fantasy roleplaying supplement details a foul sewer complex beneath a city, where characters can investigate several adventure hooks amid crumbling brickwork and polluted underground waterways. Additional appendixes provide material for expanding the presented area or creating sewer environments of any size. The supplement also includes a patron write-up for Squallas, Mistress of the Night Soil Rivers, whose domain lies beneath the streets. It is designed for four to six level 1–2 characters, with campaign elements adaptable to characters of other levels.
