Astrid's Mother

Astrid's Mother is mentioned but not seen or properly named in the How to Train Your Dragon Franchise.

Bequeathing her Axe to her Daughter
At an undisclosed time, Astrid's Mother passes on her Battle Axe to her daughter, Astrid. Astrid was using this axe by the time of the events in How to Train Your Dragon, at about 15 years old. This indicates that Astrid's mother was in part a warrior and a parent.

Loss of her Home
At some point during the episode Astrid's Team, Dagur attacked Berk, destroying several buildings, one of which was the house of Astrid's mother and father. Fortunatly, the two were on a picnic at the time and were perfectly safe. This event, however, spurred Astrid to form the Dragon Riders' Auxillary to protect Berk at all times.

Insomnia
Astrid's Mother has insomnia, and gets some Lavender from Trader Johann to make a soothing tea.

"Astrid's mother is having trouble falling asleep. A soothing cup of lavender tea should do the trick!"
