One of my duties as a shaman of the tribe is to travel to the Underworld of the Catacombs. Most of the people who want the secrets the Netwalkers have to sell live down there in the tunnels running beneath the city, some of them very old. The Catacombs date back to when the subway system in Boston was first being built and expanded. Over the years, many different tunnels were built. Subway tunnels, maintenance tunnels, sewer tunnels, and other conduits for daily necessities radiating under the streets of Boston, a whole world under the feet of the city.
