The story of Gellert Grindelwald

The story of Gellert Grindelwald
Gellerd Grindelwald, the second darkest wizard of all time. How did he learn of the Deathly Hallows? How did he rise to power? How was Albus Dumbledore able to defeat him? And why, at the end of his life, did he try to protect the one who had locked him away?
A second later, the fire released him into light. In front of him, a village, and standing before it with wand raised, laughing as it burned, a man. The sky was streaked with orange and purple, the last remnants of day. The man turned slowly, and piercing blue eyes met for the first time since that night in Godric's Hollow. So many years had passed, but each recognised the other in an instant.
