Astrid is a tall blonde, with blue eyes and an athletic build. She generally wears loose wizard's robes of varying colors, and seems committed to keeping herself and what she wears as clean as possible. She does like sturdy boots as well, though wears no jewelry. Her long hair is usually worn in a braid, tied off with leather or bright cloth. Currently she's wearing robes of midnight blue and has a black ribbon wound through her hair.

She has a very sweet disposition, and seems to be eternally optimistic. Astrid is also quite friendly, unless she has reason to be otherwise. She's not afraid to crack a joke, and seems undeterred by failure to elicit laughs when she attempts to do so.
