Travers

Travers was a Death Eater who murdered Marlene McKinnon and her family, according to Karkaroff during his own trial. At that point, Travers had already been captured by the Ministry (GF30, OP9).

Travers later escaped and partook in the Battle of the Seven Potters, where he was cursed by Kingsley (DH5).  However, he survived, and went back to work at the Voldemort-controlled Ministry of Magic, where he was a colleague of Dolores Umbridge on the Muggle-born Registration Commission (DH13); he was also responsible for the bullying of Xenophilius Lovegood after the Death Eaters kidnapped Luna (DH21).  Travers and Selwyn nearly caught Harry at the Lovegoods’ house, but were foiled by Hermione’s quick thinking.  Travers showed himself to be more cool-headed than Selwyn when he used Homenum revelio to ascertain whether Xenophilius’s claims had any merit.

Travers had a most unfortunately timed encounter with a woman who he thought was Bellatrix Lestrange, going into Gringotts, though it was actually Hermione preparing to break into Bellatrix’s vault. Harry quickly placed him under an Imperius Curse and made him hide in a crack in the wall of the cave tunnels (DH26). The curse wore off by that night, as Travers partook in the Battle of Hogwarts, dueling Parvati Patil at one point (DH32).
