A sprawling city setting for Mongoose Traveller, Second Edition, set on Amarja, a desert world on the edge of a remote solar system. The ancient city is home to gamblers, thieves, hustlers, spies, and residents of many alien species. Travellers can explore districts ranging from extreme wealth to poverty, including an international spaceport, public transport routes, markets, hotels, rescue services, and the mysterious areas of Watertown and the Settlers. The setting introduces new alien races, local landmarks, and secrets that extend beyond the city and across the stars.
