Heimerdinger’s story
A brilliant yet eccentric yordle scientist, Professor Cecil B. Heimerdinger is lauded as one of the most innovative minds and esteemed inventors Piltover has ever seen. Relentless in his work to the point of neurotic obsession, he is fascinated by mysteries that have confounded his contemporaries for decades, and thrives on answering the universe’s most impenetrable questions. Though his theories often appear opaque and esoteric, Heimerdinger believes knowledge should be shared, and is devoted to teaching all who desire it.
A place in Runeterra
Piltover
Piltover’s position above the sea routes makes trade a foundation of its prosperity. Merchant families turn that wealth into craftsmanship, architecture and research, attracting inventors from far beyond the city.
Its celebrated progress is inseparable from questions about who funds invention, who benefits and who bears its risks. Read Piltover alongside Zaun. The archived regional description and Arcane come from different publication moments, so a shared setting does not guarantee that every older detail remains current.
