Astrid Aleksandra Bjørgfinnur is a fourth year student at Durmstrang Institute.
Astrid is excitable and boisterous, probably the most bouncy of the four. She doesn't care much for books or studying and yearns for the great outdoors. However, she has considerable will— but she can be headstrong and quite fierce sometimes. She has a great deal of firepower.
Astrid was born to a pure-blooded family, alongside her 3 siblings, Eilif, Áskil, and Amalja Bjørgfinnur— they are quadruplets. They were born and raised on the Lítla Dímun, one of the Faroe Islands (Føroyar). No muggles live on Lítla Dímun, and they believe it is "uninhabited", making it a good place for Bjørgfinnurs to live. At the age of 11, Astrid and her brothers and sister all got letters from Durmstrang.
