From the Story[]
Harry Potter and the Half-Blood Prince[]
Discovered in chapter 26, The Cave[]
| “ | The potion is protected with an invisible barrier which makes it impenetrable to a human hand. Professor Dumbledore drinks the potion from a crystal goblet - halfway through the gobletful, the potion causes him to appear as though he is deeply asleep, dreaming a horrible dream. The potion causes Dumbledore to plead to stop drinking, becoming weaker and acting as though he is being attacked by invisible torturers. | ” |
