Sarah Collins appears as a young woman with fair skin, standing slightly taller than average. She has a slim and toned build, with ginger-red hair that she takes well enough care of that it doesn't knot and tangle. She's otherwise happy to let it 'do what it wants'. Although her looks are striking on their own, her skin and hair emits a very subtle warm glow that becomes most visible in direct moonlight; the only obvious hint that she's more than what she seems.
