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.
