Arla has shoulder-length red-brown hair, which she keeps pinned back but only braids it loosely in several braids. She has olive skin and freckles across her nose and cheeks. Her eyes are brown. She is fit but not overly large or muscular.
Arla is serious, but not reserved. She is young for her role and her abilities, which makes her prone to outbursts of emotion at times, though she works towards an archdruid's neutral grace.
