Pieter van Straten was a human male who ruled as the Serene Prince of Cornaro years before Harry Potter's arrival at the Great Void. He was severed after an accident during a new year's speech, many believing that the accident was nothing more than an assassination.
He had an avenue in Conference City named after him posthumously.
