Erica is 5'9" with an athletic build and her father's black hair and green eyes.  She's not always talkative, but she's charming whenever she wants to be: she's a good actress and will be a good diplomat.  (Corwin has been heard to say that she's politician like her namesake.)  She prefers to be everyone's friend, though she won't bend over backwards to do it.  She's often curious but tends to study widely rather than deeply.  She enjoys swashbuckling in Shadows where she knows she can get away with style over substance.

Her colors are green and black; her device is an upright sword with broad feathered wings, black against a green field.  She prefers to dress in those colors, but prioritizes comfort and functionality over appearance.  The one constant in her attire is a ring on the middle finger of her left hand: a wide band of silver set with alternating emeralds and onyx, a gift from Oriana on the occasion of her Walk.
