The single most important bone of contention is probably a major ley line that runs southwest to northeast across the city. This ley line follows the Fall Line, the boundary between North America’s coastal plain and the Piedmont region, which passes directly through Baltimore. This ley line funnels considerable magical energy through the city, but its focus is the large, vaguely phallic-looking Washington Monument (yes, there’s one in Baltimore, too, and it’s older than the one in D.C.). Situated on the Fall Line, in the Mount Vernon neighborhood not far from the Inner Harbor, the Washington Monument acts as both a focus and a distributor of the energy in the ley line; three additional branches reach out from that point. One reaches southeast, through Federal Hill to Fort McHenry, then under the Patapsco River to Fort Carroll. Another reaches north, through Bolton Hill and Reservoir Hill into Druid Hill Park, where it dissipates. A third runs more or less west-northwest, through the greenway around Gwynns Falls and out of the city, eventually dissipating in the hills. Magical power is enhanced all along the ley lines, but it is particularly strong at a few points: the Washington Monument, Druid Hill Park, Heritage High School and Clifton Gate House, and Fort Carroll.
The branch reaching through Federal Hill is particularly strong and, together with the Monument itself, is the focus of a very tense stand-off among the four major supernatural players in the city.
