1873 (aged 14)
Pierce Slider (1860-1873) was a Pureblooded Wizard and a member of Hellspawn. Piece was diagnosed with Mooney Madness right after turning four, and died at the age of fourteen, exactly ten years after he was diagnosed, bringing about the common belief that Mooners only lived ten years after being diagnosed. He attended Hogwarts School of Witchcraft and Wizardry from 1971 to 1873, and was sorted into Hufflepuff.
Derived from the given name Piers, which was a form of the name Peter, derived from the Greek Πετρος (Petros) meaning "stone". This is a translation used in most versions of the New Testament of the name Cephas, meaning "stone" in Aramaic, which was given to the apostle Simon by Jesus (compare Matthew 16:18 and John 1:42). Simon Peter was the most prominent of the apostles during Jesus' ministry and is often considered the first pope.
