The thestrals are creatures found in the Wizarding World of Harry Potter. They can also be found in the films featuring Newt Scamander in the 1920s in the United States. Sombrals are black skeletal horses with bat-like wings, a bird’s beak and horns on top of their heads. Despite their rather terrifying appearance, these creatures are harmless. They have the particularity of being visible only to those who have seen death in the face or very closely. For example, they are the ones who pull the Hogwarts carioles and that’s why most students think that these carioles move by themselves.
