Ten Down

A collection of ten strange subterranean destinations for Downcrawl or other underground and Underdark campaigns. Locations include a haunted library beneath shifting sand, a steam-powered city, a skeleton carnival, an undersea empire, and a maze of slime, monsters, and hidden secrets. Each setting includes a full description, a Touchstone, story seeds, notable people and places, and special rules or random tables. The collection also introduces a system for forging permanent Paths between locations, allowing characters to undertake projects that make future journeys more reliable while risking the creation of lasting hazards.
