London, heart of the British Empire, home to six-million souls, and the headquarters of many of the Leagues of Adventure, is the largest city in the world. Here, one can stroll past grand buildings, marvel at the cultural wonders of the many museums and art galleries, dine in the finest restaurants, enjoy opera, ballet, plays, and music hall performances, and mix with the Empire`s high society. Take a wrong turn, though, and one enters a world of poverty, thievery, prostitution, opium dens, and murder - a world where human life is cheap and citizens are packed into overcrowded slums like rats unable to leave the sinking ship. The Globetrotters` Guide to London is a late-Victorian Era sourcebook for the Ubiquity-powered Leagues of Adventure RPG.
