Chapter 5: The Secret of the Keyblades

The party was still pondering this problem when Aeris, seeing the Keyhole, came up to see why it hadn't been locked yet.

"How come the Keyhole hasn't been locked, guys?" asked Aeris.

"I tried to lock it, and then Sora tried to lock it, but it didn't lock," said Riku.

"I heard something about when two Keyblades have appeared before," said Aeris. "When there are two Keyblades, they must be used at the same time to lock the Keyholes. Try it and see."

Riku looked at his friend.

"Ready, Sora?" asked Riku.

"You know it, Riku!" said Sora.

They both pointed their Keyblades at the Keyhole. To everyone's surprise, both Keyblades shot a beam of light at the Keyhole, and the sound of a lock locking came to their ears. Riku and Sora looked at each other and then to Aeris.

"It worked!" said Riku.

Aeris nods. "Because Shade revived the Dark Keyblade and managed to reopen up the Keyhole, it's going to take the power of two Keyblades to lock the Keyhole up once again. That was why Sora got his Keyblade," said Aeris.

"Well," said Riku. "I guess it's time to pay Cid another visit. We're going to need his Gummi Ship to get to the other worlds so we can seal them up."

The party nodded and headed to Cid's place which was on the outskirts of town. After explaining to Cid what was going on, they boarded the Gummi Ship and headed off to find out which worlds were becoming infested with Heartless and seal them back up.
