Professor Talon
Arthur Talon, Defense Against the Dark Arts teacher. Born in 1964 as a pure blood he was not bothered by death eaters throughout most of his life, although he did protect all muggle-borns that he could. He went to Hogwarts at the age of 11, he was in Gryfindor and graduated the same year as Harry was born. After Voldermorts defeat once and for all and Hogwarts was once again short a defence against the dark arts teacher Arthur became a professor. He went on to teach students, including Harry Potters children, for many years and became head of Gryfindor House. He also was the first professor to teach Defence Against the Dark Arts for more then one year in a long time, and used a few charms so as to not look any older then he does in these photos (to explain the slight plastic look...)
(Sorry for the fuzzy photos. The cameras a few years old.)
