The Last Battle
A wicked monkey named Shift convinces a unknowing donkey named Puzzle to dress up in a lion's skin and pretend to be Aslan, the great lion. This trickery causes the undoing of Narnia. The King and his friend, Jewel the Unicorn, are captured and the neighboring country of Calormene is able to invade and use the Lion to terrorize native narnians. King Tirian is unhappy and captured when he calls for the children of earth to come to Narnia and help him. Eustace and Jill, heroes of The Silver Chair, appear and rescue him. They then rescue Jewel and take Puzzle. Puzzle apologizes for his stupidity claiming he's "not very clever." They then try to prove that the ape has been lying to them about Aslan to some passing dwarves. The dwarves believe them but don't believe in Aslan after that and make the slogan "the Dwarves are for the Dwarves." Only Poggin the dwarf joins the group. They then go to the stable, where the Aslan has been kept since he appeared. Shift then says that anyone who wishes to see Aslan must go into the stable. A devious cat named Ginger volunteers (he is in on the plot with Shift.) He goes in and comes out dumb and unable to speak. Then a young Calormene goes in (to see Tash, the calormenes God, whom the ape says is the same as Aslan) and another Calormene is tossed out from the inside, dead. Then as they start to send in other beasts to whatever terror is there Tirian and his group come out from hiding. The monkey is thrown in the stable. Then the last battle of Narnia begins. During it most of the good forces are killed and the children are thrown into the stable. Tirian is finally forced into the stable where he sees the evil Tash. Tash is then sent away suddenly. King Tirian finds Peter, Edmund, Lucy, Eustace, Jill, Digory and Polly all there (Susan has forgotten Narnia.) Then Aslan appears and puts an end to Narnia. They then travel to a new Narnia where they find all the good creatures of Narnia from all the previous books. They live happily ever after.
