Hogwarts

Hogwarts also poses dangers. The Death Eaters are led by Voldemort (he who must not be named, or as the Death Eaters call him, "the Dark Lord"). Bellatrix Lestrange, Lucius Malfoy (Draco's father), Severus Snape, and Barty Crouch Jr. are also there.

Voldemort killed Harry's parents, leaving a lightning-shaped scar on his forehead, and dreams of killing him.

Draco Malfoy is popular because of his parents. It's dangerous to argue with him. He's a bully. He constantly picks on Harry and the Gryffindors.

Inhabitants:

Buckbeak: A bird with wings and a beak. Most often white.

Dobby: Dwarf, has an owner (Malfoy's father.)
