Astrid's Great-Grandmother is mentioned only once in the game, School of Dragons, as part of the Quest "History of Viking Contraptions". Her name is unknown.
At some point in Astrid's Great-Grandmother's life, she was alive at the same time as Astrid. She bequeathed her comb made of durable Red Deer Antler to her.
- "You need my comb for the new class? Sure! Vikings have been making combs for years, but this one is special. My great-grandma gave it to me!"
- ―Astrid in "History of Viking Contraptions"
