They mark out the main routes between Tau [[sept]]s and are used to speed communications between outposts.*'''Nicassar Caravans''': The [[Nicassar]] trading caravans Caravans are large networks of conjoined [[Dhow]]s which the aliens employ when traveling over long distances at their natural leisurely place. Occasionally Caravans will accompany Tau fleets to war, and if attacked a Dhow Caravan may detach to fight in the defense of their community. They are so slow that they are considered practically immobile in space combat.
