Mylittlepony
From ShireWiki
Mylittleponies roam the grasslands and the lower hills of Maraguo, they are the national animal of that nation. The origin of the beasts on the island is vague, but most likely a strain that survived an ancient shipwreck interbred with animals imported by early settlers.
Many herds are feral, and some can become a bother to farmers. Easily re-domesticated. They rarely slaughtered (except in times of famine) but they are often milked. The milk makes Ponykaas, an excellent multicolored local cheese. They make excellent beasts of burden for small loads.
Larger and more fierce ponies were used by the vryholders as beasts of war in the MKP cavalry.
