Battlemap of a Caravan Inside the City
This caravan probably just finished a long journey to Ptolus. Caravaners like those from the Rogue Moon Trading Company, look forward to rest and good trade, and the caravan guards dream of visiting a good tavern. No one would expect an attack from bandits inside the city!
