Silk Road (d20)
A Magical Society: Silk Road is a 160 page supplement detailing great overland trade routes. Borrowing extensively from the caravans of Central Asia¸
A Magical Society: Silk Road covers a variety of topics: what factors engender great overland trade routes¸ what elements accompany the existence of silk roads¸ and how do caravans function on the road (with consideration to terrain).
