From the back cover:
"Designed for all fantasy roleplaying systems, Carse is a home base for adventurers. With it, gamemasters present adventures normally, using CARSE to locate shipbuilders, outfitters, armorers, ins, sorcerers, and all the other delights which player-characters demand.
"Nearly one hundred kinds of businesses and professions are noted; in all, about 450 buildings and four major complexes have been populated and discussed.
"But Carse is much more than a medieval shopping mall. A lively city-state, romantic intrigue and secret societies abound here, each with its own prescription for love or power, and each in turn shadowed or hounded by the operative of Baron Bogardis IV, capable ruler of Carse. Gamemasters can use it sub-plots and random encounters to generate new scenarios. Lovers, thieves, thugs, loonies, and even a few honest folk strut down byways where personal schemes and family connections are all-important, yet who can say whether it is good or ill to be known by such residents as the Troons or the Hazara Khans?"
