The Potions master at Jagiellonian University was a large bear of man named Mikolaj Brukowski. He’d been famous for the invention of Bru-Bier, a popular Eastern European beverage that was similar to butterbeer but a good deal stronger than anything found on tap at the Three Broomsticks. Hermione’s sudden improvement in his subject had seemed to impress the old wizard, and she’d soon become his personal protégé. By the end of her fourth year at university, Hermione and Brukowski had jointly published two papers in the prestigious Bibliotheque de Remede Europe & Worldwide (BREW): one on their discovery of an additional four uses for dragon’s blood, and another on a potion-brewing methodology that had rocked the wizarding world and had even garnered them a small feature in the Sunday edition of the Daily Prophet.
