Dwarven Caravans

The dwarves of Godai, especially those of Azuth, create amazing toys and clockwork items which are loved across Godai, and there are many travelling carvans, which sell and trade such items to the populations of villages and towns across all the continets of Godai. Such items can be simple clockwork men or animals as toys for children, though to more complex creations used as short term guardians and watchers, able to raise the alarm if someone or something crosses they line of sight.
The Caravans are simple constructions of wood and metal, pulled by strong hearty horses, or the large mountain goats found in the dwarven homelands, but they found across the world all the continents, some permanently travel around the roads of each continent, while others return to the dwarven homes in the north. Those that stay in the kingdoms, trade with other dwarves within the cities and traders from the homelands for new goods and to sell traded items back to the dwarves. As while the Dwarven homelands can provide the basics of living many of the more specialist items are hard to come by, like woods and leathers. Along with items of beauty rather than functionality, gem set jewellery and the like.
Children know that the dwarven caravans bring interesting things more so than other traders, so they often save their pennies for the one caravan a year that may turn up within their village, some may go years without seeing one, due to the remoteness, the dwarves see little profit going to the more remote places so rarely travel those places over more populated and wealthy areas of the world. When the Dwarves bring new clockwork toys to a village that may not have seen such new items in years, there is a level of general happiness from everyone, the dwarves will always try and find a way to make a trade work for themselves, if hard coin can't be traded, many of the outlining settlements rarely use money instead work on a bartering economy, so the dwarves will find items of use to them and exchange goods in value rather in the prefer coin. Some of these goods they will sell in the next village or further round their route, some will be returned to the homelands depending on what value and need there is.
