Cinnabar
Considerably smaller than most centaurs, and different in that instead of hooves she has paws, a fine felt like fur and a significantly larger number of metal plates than most would wear.  Her upper body is wearing a suit of field plate sized appropriately for a halfling or gnome, and it seems to fit quite appropriately on what is overall about the size of a very large dog.  Fighting primarily with a lance she also keeps a crossbow within easy reach at her side in what is obviously a very customized holding device.
