"It was through me, you see, and our bond as Triwizard Champions, that Dumbledore first came to meet my father, Nicolas. They hit it off immediately ... Albus was always intoxicated by meeting powerful wizards who were Masters of arcane crafts. That is why his connection to Gellert was so strong. My father, as a Master Alchemist and the only known producer of the Philosopher’s Stone, was a source of deep fascination and reverence for a knowledge-thirsty young warlock like Albus. He apprenticed with him for ten years, though their work and friendship lasted until my father’s death a decade ago."
