Look, it's simple:

See that fat lick over there?
With the backpack?
When he steps onto the black asphalt of the parking lot, he's mine. Until then, he's in the fields, where any vampire can take him. I am the lord of this ground, and the penalty for poaching from me is you must drink from me. When you drink the kine that walk on my ground you drink from me.
— Sycorax, Lady of the Blacktop

The City-creation sourcebook for Vampire: The Requiem

The Prince is the master of the city, but he has named you lord of your territory. It's up to you and your cohorts to maintain the Masquerade, influence mortal lives and pass judgment on the Kindred who dwell in your shadow. Are you a tyrant or a saint? Will you pull the Prince's strings or become the Prince yourself?

This book includes:

• Guides to selecting or designing a modern city that's right for your chronicle, and giving that city the World of Darkness's gritty supernatural atmosphere.
  
• Tools and tricks for running dramatic and suspenseful stories in a crowded and shadowy city, including such new systems as "City of Millions" and "Attitude and Ambience."

• A guide to the fictional city of Newcastle—a new World of Darkness environment ready for you to customize and activate in play.
