I don't own DBZ, any of their places or characters, etc. I do technically own Tempest/Tomo Lorien though. :)
Not much of DBZ is mentioned in this fic though.
There are 5 Chapters.

Tempest Book: First Fire

Chapter Four: Revelation

"Why? You of all people, my friend, would try to destroy me? I have so few friends as it is." Tomo glared at Sen, the traitor. Sen dropped Kila again. "You ignored me! But it isn't just that. No, that was just the final straw." Sen's voice was still bitter. Tomo thought about how powerful Sen must be if he could use such an advanced attack at such a young age. He got angry.

Sen continued his lecture. "I almost changed my mind about killing you. But when she followed you, even after the argument you had? Yes, I was there, listening. How pathetic, nature never has tried to help anyone, yet you both think it special. I thought that argument would end your relationship for good. But she had to have a change of heart, and go after you. Well, I decided that I wouldn't allow that, and here we are."

Kila looked up at Sen sadly, feeling a little sore from hitting the ground again, but stood back up. "I didn't know you cared so much, but you of all people must know my feelings. And now, I could never love you. You were my friend, but you have shown you do not deserve my friendship, nor Tomo's."

Tomo was shocked again at Kila's speech. 'Her feelings? That must mean..." he thought, but looked on as Sen smirked. "I see. Well, it is too late to be my friend now. I have already made my decision. You will both DIE!" Tomo ran toward them in horror, trying to stop Sen from his attack, but he was too late. The red blast was quicker this time, and not at Tomo.

Time moved slowly. Tomo ran forward, Sen shot the blast, which flew straight at Kila. It blasted straight through her heart, and continued at Tomo. His sadness, though, spread out into his aura, and blocked the laser. This surprised him, but he couldn't stop. Kila fell slowly to the ground. He stopped her fall, cradling her in his arms. Sen looked on with amazement, and with partial joy.

Blood stained the front of Tomo's shirt as he held her. She struggled to hold on for her life, and managed to start talking, mostly mumbling. "Sen...you...bastard.... Tomo...calm...storm...both are needed...to live a good life. I am glad...I found both...the sun sets...."

She said no more. He wished she hadn't said that. Sen just looked on, waiting for Tomo to confront him. "You did this," he yelled, getting angry from the sudden sadness that had set in on him. "YOU DID THIS!" He yelled louder. Sen just laughed.

"Yes, I did, and it should have been you too. But I guess you are stronger than I thought. So, I will unleash my full attack!" He raised his hands, and the energy he gathered increased in size, until it was as big as a basketball. Sen screamed as he fired it at Tomo.

Tomo yelled. "You have hurt enough people. You will not hurt me too!" He watched the attack come at him, and knew he couldn't dodge it. He knew what to do. The fireball came at him like a rocket, and he punched it with all his rage, anger, and sadness. The explosion was great, but not at him. The ball deflected, and flew up out of the small city. It exploded high up in the air, bigger than Tomo had thought it would be. Sen just looked on in shock. Tomo, with ever increasing anger, jumped up high, and landed next to Sen. "No more pain. For me, or for you. I'm going to end this now."

He gathered up energies that he didn't know he had, from the nature he loved so much. Sen looked at him in fear, knowing that he couldn't even hurt him. He realized the potential of Tomo's true power, and tried to attack him. Tomo was too fast for him though, and dodged easily. Sen would be the first to see his power, but not the last. He put in as much energy as he thought he had, and slammed Sen hard in the stomach with his right fist, which sent a ripple of energy through Sen, sprawling him over. Tomo then went totally insane for the moment as another surge of energy rushed through him, a power of pure light that he didn't know existed in him. He moved away from Sen, who was doubled over in pain, and blasted the light energy at him. As the light hit, it twisted and contorted Sen's body, and he was totally disintegrated.

The light disappeared, leaving nothing left of Sen or Tomo's mysterious attack.
