Bosanc horses are the largest of all horses.  They are bred in and near Traigar.  They are prized as war horses, since they are capable of easily carrying full armored knights into battle.  They have long hair compared to other horses and a typically mean temperament.  They do not survive in warm climates well, though they can handle temperate zones.  Some knights have been known to keep them shaved, which helps in the warmer climes.  They do not take to running and typically only walk, but they will charge into battle without fear.  They are named for the tribe that first domesticated them.
