Ghost of a flea

As the old splash page said: The city sprawls in all directions, a hectic mass infecting the earth it rests on. The buildings reach above and the tunnels burrow below. In this city the citizens run madly, ignoring the back alleys, tunnels and buildings of yesterday. Unknown to them, beyond that decaying door frame or small metal portal await adventure and sights few will ever see. All it takes to step across into this parallel world is a torch and a curious spirit. No joining fees, no ridiculous contracts and nobody looking over your shoulder. You might be surprised how little of your city you have ever appreciated.
