Invisibility
The state of being magically unseen, reached through an Invisibility Cloak, or charms that blend a person into the background.
Invisibility is the state of a physical object being magically unseen. Wizards reach it by several routes: an Invisibility Cloak, the Invisibility Spell, or a Disillusionment Charm or Bedazzling Hex, both of which come close enough to pass. The Hogwarts library keeps an entire Invisibility Section. Some invisibility is conditional rather than absolute, working on certain onlookers and not others. Thestrals stay unseen by anyone who has not witnessed death, and Dementors are invisible to Muggles while witches and wizards see them plainly.
