War Horse - Mars

"There is a wolf in me... fangs pointed for tearing gashes... a red tongue for raw meat... and the hot lapping of blood - I keep this wolf because the wilderness gave it to me and the wilderness will not let it go". Carl Sandberg, Wilderness
Wild horses are so impressively wild. We don’t think of them the way we think of wolves - but "Mars" is like a wolf. This horse has teeth for tearing gashes. I can feel the wind winding up the mane and tail - whirling the hair into a frenzy that would drive an animal mad and set them running - so dangerous and so beautiful. A primordial steed with a battering ram as a chest plate for battle.
This creature is an ark, self contained and mobile.
