At first, it was an accident that brought Blood Oath to Black Swan Port and into the hands of the king. He used two parts of his blood-sworn genes to create a child - Gellert Grindelwald. Grindelwald survived the explosion, came to Cassel Academy, and created the Grindelwald family. This is a story about Percival Grindelwald, the grandson of Gellert Grindelwald II.
Everyone in the Grindelwald family looks like AD (except for the wives who married in)

The timeline of this dragon clan is messy. I have only played the game and never read the book.
Concept: I love Harry Potter, I love dragon fantasy... Map
