Unidentified Thestrals

These thestrals were used by Harry Potter, Ronald Weasley, Hermione Granger, Ginny Weasley, Neville Longbottom, and Luna Lovegood to fly to the Department of Mysteries after Harry had a dream about Lord Voldemort torturing Sirius Black. They were drawn to them by the giant blood soaking Harry and Hermione.
