Renfri is a melding of many different horse breeds and her structure leans mostly towards her Arabian, Mustang, and Andalusian ancestors. She has a thick, stocky build and a pretty, refined head. Her eyes are bright pink and she has a slightly crooked horn that is so black it seems to absorb all surrounding light. Her coat is a deep space blue and her feathered wings are several shades darker than her body. She also has a crooked halo that radiates a more electric-blue color, and is surrounded by a dark aura.

Renfri is a trickster who enjoys making others uncomfortable. She uses her abilities to make others' emotions run wild and likes to cause trouble wherever she goes.
