The airship was gliding down through the sky. Then it tilted abruptly. No, the figure inside thought, that's not gliding. That's crashing. Then a piece broke off. The figure whacked against the side of the airship. A gap in the hull was right beside him. He looked out of it, trying to find an island to land on. That, or land on. A large island suddenly came into view. The problem was, he had been over it when he just now spotted it. The airship was almost over it. Nothing else for it, he thought.

He jumped. The words of one of his fellows came through his head.

"They allowed me to pick, you know. Let me choose whichever Toa team I wanted. I chose our team because of you, brother. You were capable. Not as capable as our leader, but capable enough. But hurry back. Otherwise, aren't you capable? Was I wrong?"

Keora, Toa of Sound, fell to earth on Mata Nui.

Tahu was sleeping in Po-Koro when he heard a tremendous explosion. He ran out of his hut to see a fireball rising into the air a few minute's walk from the village. What was that?

He ran to the spot and was joined on his way by Takanuva and Jaller. "What was that, Toa Tahu?"

Tahu shook his head. "Don't know. I'm going to find out."

Keora was writhing in the crater he had made. For some reason, his mask had released a massive discharge of sound that had exploded the air around him, and the feedback was excruciatingly painful. He finally was able to master the pain, and took his laser crossbow from his back.

A branch snapped. Keora turned his crossbow on it, and fired a bolt into the woods. After a split second, the bolt rebounded into the crater and hit a tree, disintegrating it.

"Peace, brother. We mean you no harm."

Tahu stepped out of the bushes, and took at the downed Toa. His armor was all silver except for his mask, which was a dark gray. The mask was elegant in its design, two raised sections sweeping back to a point on the back. On the face his eyes were in a sort of sloped, right triangle. A small circle allowed him a hole to speak through. A short, fin like shape moved up the center of the mask. The eyes narrowed. "Who are you?"

Takanuva and Jaller came out of the bushes, and Keora turned the crossbow on them. "Get back!"

Tahu lifted his hands. "Hold it, brother. We're not going to hurt you."

Keora tried to respond, but fell back, unconscious.

"Takanuva, help me carry him."

The two Toa picked the wounded Toa of Sound up. Jaller scuttled around the clearing, trying to find something to do that would seem useful. Tahu called back to him. "Come on, Jaller. We may need help."

Keora woke up in a vastly different setting. Where he had seen lush and wild jungle was now stone. He moved a hand and felt a bed under him. A Matoran was sitting on a stool beside him, and blanched as one of his eyes locked on to her. "Who are you?"

"H-h-Hahli."

Keora smiled and clasped the small Matoran's hand in his own. Hahli seemed to grow nervous. Keora cocked his head. "What's wrong?"

"You pointed your weapon at my friends." she said, pulling her hand gently from Keora's grasp.

Keora could see his crossbow on the wall across the room. There was a knock on the door. "Hahli, is the Toa awake yet?"

Hahli looked at the door. "Yes, he is."

The door opened and Jaller walked in, followed by Turaga Vakama and Tahu. Jaller stood beside Hahli and absently grabbed her hand. She didn't notice. Vakama walked up and put a hand on Keora's shoulder. "Welcome to Mata Nui, my friend. What is your name?"

"Keora. Toa of Sound."

Tahu pointed his sword at Keora. "All right, start talking. What are you doing here?"

Keora looked at the sword and widened his eyes. The Matoran covered their ears as a loud blast of sound blew through the air. Tahu's sword shot out of his hand and buried itself in the wall. Jaller leapt on Keora's bed and pointed his sword at him. "What did you just do?"

Keora narrowed his eyes, and his mask began to glow. He jerked his head to one side and the Ta-Matoran flew through the air to land at Tahu's feet. Turaga placed a hand on Keora's. "Easy. Toa Tahu is a bit brusque. "

Keora sighed. "I'll tell you where I come from. I am from the island of Jora Nui, an island that even as we speak is under attack."

"From who?" Jaller asked, getting up.

"An army of our greatest enemies. Rahkshi, Visorak, and Bohrok. I've come to ask for help."

Vakama turned to Jaller. "Go to the other villages, Jaller. Ask for the other Toa to gather here."

The Matoran saluted and ran out of the building.

Keora tried to stand. Tahu sat down beside him. "Steady, brother. You're not ready to go yet."

"He's right," Hahli said. "We'll wait until the other Toa get here."

Keora touched his mask. It was the Kanohi Heya, the Mask of Ability. With it, he could teleport, move objects, and multiply himself. There were other uses. Many others. He tried to stand again. Tahu pulled him down. "You're not ready yet. Lie down. Rest. We'll call you when we're ready."

Keora nodded. Vakama patted his knee. "Rest my friend. Watch him, Hahli. If he needs anything, send for me."

Hahli nodded. "Yes, Turaga Vakama."

Keora nodded to Vakama. "Thank you, wise one."

He lay down and looked at Hahli. "You remind me of a Toa that I know back home. She was as determined as you are."

Hahli looked surprised, but didn't say anything and patted the Toa's hand. "Go to sleep. I'll be right here."

Keora obliged.
