Cessernante horses are bred in the Southern Plains and sold throughout the world as riding horses and race horses.  They are very sleek with thin legs.  Breeders mark two major lines:  one all black, and one all white.  Roan and black and white spotted are rare and typically put to death.  They have long manes, but very short hair elsewhere.  They drink an inordinate amount of water, making them of little use in the deserts.  They were named for the river where the largest breeding facilities are.  They have a surprising stamina and endurance, but relatively little strength.
