Hogwarts: I Became the Third Dark Lord.

Wentworth Grindelwald had many illustrious titles throughout his life:
The greatest prophet of our time, successor of the Vigilantes, leader of the Secret Society, heir of the Grindelwald family, and—the third Dark Lord!
He had London draped in black veils, and the sorcerers reappeared in the wizarding world;
He established the Secret Society at Hogwarts, monopolizing the magical talents of an era;
He faced off against the second Dark Lord on the Rhine, where nearly half of the Death Eaters defected.
He strolled beneath the Tower of Nurmengard, his followers welcoming Gellert as he emerged from the tower;
Wherever his wand pointed, countless believers pressed on without hesitation.
The Daily Prophet: This is the worst of times; he is leading wizards to destruction!
"The Quibbler": This is the best of times, and he is leading wizards to a new era!
Wentworth Grindelwald: I'm not! I didn't! Don't talk nonsense!
