A herd of domesticated Thestrals resides at Hogwarts, and they’re used to pull the carriages for the students from the train station to the school. They’re black, have no flesh, and their skin clings directly to their bones. With their white eyes, bat-like leathery wings, and carnivorous appetites, they can appear very ominous, except for one thing: they’re invisible to all, unless the person has witnessed a death.
