Talisman 4th Ed. - The City Exp. - Rules of Play says:
For the traveler with some gold to spend, a visit to the City can give him the edge to survive in the most dangerous regions of the land. The opportunities one has within the City’s walls may make the difference between life and death in the Valley of Fire while peril and wickedness await. Talisman: The City adds a new Region to the game for venturesome heroes to discover. A custom-fitted map board and over 100 new cards bring this bustling metropolis vividly to life. Six brand new characters, each represented by a superbly detailed plastic miniature, offer fantastic new playing experiences.
