The three friends discover that Hagrid is raising a baby dragon, which is against wizard law, and arrange to smuggle it out of the country around midnight. Draco, hoping to get them into trouble, tells Professor McGonagall. Although the dragon is safely away, they are caught outside of their dormitory. Harry, Hermione, Draco, and Neville (who, trying to stop Harry and Hermione after hearing what Draco had been saying, was caught by McGonagall as well) are punished by helping Hagrid to rescue a badly injured unicorn in the Forbidden Forest. They split into two parties, and Harry and Draco find the unicorn dead, surrounded by its blood. A hooded figure crawls to the corpse and drinks the blood, then moves towards Harry, who is knocked out by an agonising pain in his scar. When Harry regains consciousness, the hooded figure is gone and a centaur, Firenze, offers to give him a ride back to the school. The centaur tells Harry that drinking a unicorn's blood will save the life of a mortally injured person, but at the price of having a cursed life from that moment on. Firenze suggests Voldemort drank the unicorn's blood to gain enough strength to make the elixir of life from the Philosopher's Stone, and regain full health by drinking that.
