Miraculous Steed

A long time ago, there used to be a kingdom called Gyord. This kingdom viewed the common horse as a powerful god that ruled the lands. However, because this kingdom thought that way, they were ridiculed and hated by neighboring kingdoms. The other kingdoms wanted to rid themselves of such idiocy. Therefore, they replied in violence to the Kingdom of Gyord. However, the kingdom wouldn't fall. Each time a battle took place, the kingdom would destroy all it's enemies except for the horses. They would take horses and place them somewhere unknown to the rest of the land.
Its been about 200 years since then and a young boy, about the age of 14, named Thomas, wants to set out on a journey to find these missing horses. Although most of the townsfolk believe that all horses have gone extinct, Thomas hasn't given up hope. Along with his best pal, Will, both set out to find these "mythical" beasts.
