Breeds:
Because populations both human and equine were decimated in the Great War, pedigreed horses are in short supply and high demand. Horses of true breed type and lineage are generally reserved for nobility, soldiers, the weathly, and those who are good at stealing or bartering. The majorty of the population has to settle with 'grade' horses, animals of no particular breed or lineage. These can still be fine animals but hold a lower social status and typically sell for less money than a purebred.
For our purposes, horses both purebred and grade will be split into five catagories: Draft, War, Carriage, Riding, and Pony.
Draft Horses are big, heavy, massive animals. They are often seen working in the fields, assisting in farmwork and other labor. They are also used to pull heavy carts of raw material and supplies (think coal, timber, etc). While they can be ridden they aren't the most comfortable.
War Horses are typically 'warmblood' type horses. Slightly larger and more substantial than a riding horse without loosing too much agility or speed. As the name implies they are used in battle. They can easily carry the weight of an armed solider while performing precise movements to their rider's demands.
Carriage Horses are generally tall and pretty. They are too fine to make good draft horses but look nice in front of ornate carts. These are a luxury animal.
Riding Horses are just that. Animals of average size and build used for riding or pulling smaller carts.
Ponies come in two types: Short And Hairy and Slightly Taller And Less Hairy. Ponies make good riding animals for children or people of dimunitive stature. Despite their size they are amazingly strong and can be used to pull loaded carts, with the added benefit of requiring roughly a third of the space and feed their larger counterparts need. They're also used in mining to pull raw material from shafts too small or narrow for normal horses.
