Duel at Godric's Hollow

The duel at Godric's Hollow was a three-way duel that took place in 1899 between brothers Albus and Aberforth Dumbledore, and the future Dark wizard Gellert Grindelwald. It resulted in the death of the Dumbledores' fourteen-year-old sister, Ariana. After Ariana's death, Grindelwald fled Britain.

For ninety-eight years afterward, the results of this duel haunted Albus. He never knew who had in fact uttered the curse that had killed his sister. This had produced fear in Dumbledore, causing him to take forty-six years to finally stop Grindelwald.
