Prince Rillian then confesses to his mistress that he destroyed the chair, and proceeds to tell her that he is no longer her slave - but is the rightful heir to the Narnian throne. The witch then uses her spells to convince Eustace and Jill that the "other world" (their own world and Narnia) does not exist, and that her world (the underworld) is the only world. Puddleglum then defies the witch, only for her to knock him out with a vicious spell. She continues to hypnotise the children, while Puddleglum regains consciousness and places his hand in the witch's fire, screaming: "Aslan!" The witch's spell on the children is crushed and they regain their memory of the overworld. Puddleglum then continues to tell the witch that he definitely did live in a place called Narnia, and even if there isn't such a place, then it is far better than the "black pit of a world" that she could come up. He finishes his taunt by stating: "We four can create a dream world to lick your real one hollow!" The witch is furious that Puddleglum has threatened her, and as he and the other three proceed to leave, she turns into a serpent but is quickly killed by Rillian. The prince then realises that the serpent who killed his royal mother was no other than the Lady of the Green Kirtle. They then flee the apartment, but everything suddenly starts to rumble and the roof is falling down - because the witch had ordered her slaves to dig through the roof of the underworld for an invasion of the overworld. Earthmen are panicking and running all over the place outside, but the four overworlders manage to get through the carnage and reach a patch of light near the very top of the overworld. Jill goes first and the others notice that she disappears. Eustace follows her through and they are helped through the gap by two fauns. They shout back to the others that they are in Narnia and when they come through, Glenstorm the centaur instantly recognises the last one of them as Prince Rillian.
