Herds are a resource, and the most basic component of your clan's wealth, consisting of cows and goats. The cow is the basic unit of currency in Six Ages, and your herds are listed by a numerical value equal to the number of cows you own.

Herds will grow on their own over time, assisted by an investment in herd magic during Sacred Time, as well as Busenari's Calf Blessing and Uryarda's Kid Blessing. Fully-grown cows and goats provide a steady supply of food in the form of milk, and can be butchered in an emergency to provide additional food.

Because of their value, cows are frequently sacrificed to the gods, offered to other clans as gifts, or exchanged in trade. Most raids aim at acquiring a rival clan's cows.

Other clans in the Valley have their own herds. In addition to cows, the Rams also keep sheep, hence their name. The Pure Horse clan keeps no herds at all, preferring to own only horses.
