From the back of the package...
A fantasy city can be a vast, sprawling, mazelike place. Main streets turn into blind alleys. Thriving markets adjoin crime-infested slums. The wise traveler avoids problems by consulting his Trail Map.
TM4 maps out not only the grand city of Waterdeep, but also to other cities featured in the Avatar Trilogy: Shadowdale, fabled home of Elminster the Sage, and Tantras, a bustling port on the Dragon Reach.
All maps are full color, printed on a 36" by 57" sheet suitable for use in gaming or as a wall poster.
