Walker

The tamed buckskin Tennessee Walker had been wondering around in the wild. He had been thriving off the lands, with no humans around. He noticed his spirit becomming wild, but not fully. He was born captive, held captive, and raised captive by humans. He seeked new humans.
As he walked into the barn area, the new scent of other horses and fresh grass came to his nose, as well as the trickling sound of water coming to his ears as he chewed at some grass. He reared halfway before landing back down with a thud. His wildness was overtaking him, but he still had the smarts to stay away from bad humans.
