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.

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!"
