Baptism by Fire
Perhaps the most desired feature of a Haven in the Twin Cities is access to the Labyrinth. The Labyrinth is a series of seven distinct and interconnected tunnel systems that run beneath the four prefectures. They consist of telephone tunnels, water main tunnels, power and gas line tunnels, the sewers, and a series of hidden caves. The first tunnels built were the sewers, begun in the nineteenth century to drain sewage and storm-water run-off to the Mississippi. Most tunnels are large enough for a man to walk upright in, though most are tight. The largest, though, can be up to eight feet in diameter.
These tunnels, dug directly into the limestone upon which the Twin Cities are built, create a bewildering maze beneath the streets. The Labyrinth is multi-leveled, with bare-rock tunnels from the nineteenth century joining up with brick-lined sewers and modern utility tunnels. Passages dead-end, connect at random, split up, and change shape without any seeming pattern. One tunnel system may be above another system in one area and beneath it somewhere else. The various levels are sometimes connected by shafts.
There are few access points into the Labyrinth, and many of those were made by vampires for safe travel and secure entrances and exits into their havens. Not all of the access points are known, for exploration of the tunnels is dangerous indeed. Not only is there the risk of getting lost, but there are also rumors of creatures strange even to the undead. Thus, most of the commonly used pathways through the Labyrinth are guarded secrets, passed from mentor to protégé. A vampire does not often reveal a passage from his or her Haven into the Labyrinth… though it is said that each of the Regents of the Prefectures can get into the tunnel system.
