Valkstrid

Valkstrid is the femslash ship between Astrid and Valka from the How to Train Your Dragon fandom.

Canon
Before they properly met each other, Astrid had heard a few about Valka while growing up on Berk with her son Hiccup. Like from whenever Stoick talks about the pain of missing someone or the need to protect after failing to save the people they care about. When Astrid had learned that the item Stoick was waiting for Johann to bring him was from his long lost wife, she helps Hiccup and the others find it. After Astrid and Hiccup officially became a couple, Astrid is given the betrothal gift that Stoick had once given to Valka, before passing it onto his son. Astrid is touched by the sentiment when it was given to her and felt honoured that she is being entrusted with an item that once belonged to Valka.

While everyone on Berk believed Valka to be dead and told their children so, the chief's wife was actually alive and has been living with dragons for the last twenty years. Without having any contact with any of the people from Berk, because to the events that happened on the night she was taken from the island. In which prevented her from learning of the changes that Astrid helped Hiccup to make for both humans and dragons alike.
