GOOD PREVAILS
Aragorn and Gimli went into Minas Morgul to kill the Witch-King and to capture or destroy the Palantir. But, they both first had to deal with the Nazguls. They fought hard, defeating the Nazguls one by one. After all the Nazguls were defeated, Aragorn went to kill the Witch-King while Gimli looked for the Palantir.
Aragorn found the Witch-King in the throne room. "You think you can kill me?" hissed the Witch-King. "I know I can," replied Aragorn. They both fought. The Witch-King kicked Aragorn down. Aragorn's sword flew out of his hands. He grabbed his elven dagger and stabbed it at the Witch-King's leg. While the Witch-King wreathed in pain, Aragorn reclaimed his sword and stabbed the Witch-King through the heart. The Witch-King shrieked and exploded into nothing.
Meanwhile, Gimli found the Palantir in a tower and smashed it with his axe. Gimli then rejoined the battle outside. The forces of good were winning the battle as the forces of evil weakened. After the death of the Witch-King, the evil army lost its will to fight and fled. The good army pursued them and defeated them all.
"We have succeeded! Evil is no more!" yelled Aragorn. The army cheered. Finally, there is peace in Middle-Earth.
