Astrid is tall and slender, like her mother's people, but wiry and powerfully-built, like her father's. Her skin is lightly tanned, likely from hours spent on the decks of sailing vessels, she favors simple, unassuming clothing, and is never seen without her father's greatsword, a relic from Rashemen that's clearly seen better days, but is lovingly and reverently cared for to the best of Astrid's abilities.

Her hair is long and red, and Astrid keeps it tied up in braids whenever possible, to keep it out of her eyes. The eyes in question are fierce and green.
