Harriette Alvenheim is a woman in her late thirties, or so she appears. She is taller than average and her frame is average to a little heavy, though not unpleasantly so. She appears fit and strong.

Blue eyes and raven hair highlight a pretty, though not overly pretty face with just a hint of crow's feet creeping in at the corners of the eyes. Laugh lines are beginning at the corners of her mouth, though it does not detract from her attractiveness. She appears to be aging well and gravefully.

Harriette prefers silk shirts and to dress in dark blue or gray with little jewelery or adornment. She carries a plain dagger always and has magical geegaws hidden about her person for easy use.
