Luna and Celestia were both pretty high up now. Celestia had almost caught up. Luna whipped around and fired a beam of dark energy from her horn. Celestia rolled to the side and dodged the attack. The two sisters continued firing at each other, lighting up the sky. From down below it looked like a massive thunder storm. Luna shot passed her sister and kicked her in the side. Celestia flapped her wings repeatedly to keep her balance. She dove as Luna shot passed again. She spun around and fired a beam of light energy at Luna. The beam shot passed her head. Luna spun around and fired a beam of dark energy. Celestia did the same but with light energy. The two collided, causing a flash. The two beams struggled to overcome each other. Luna concentrated her energy, making her beam start to over come Celestia's. Celestia struggled against Luna's power.
"Give up, sister!" yelled Luna. "We always knew I was the most powerful!"
Celestia flicked her head to the side, causing both beams to strike the ground below.
Twilight and her friends reached the castle gates and turned around. The sky flashed repeatedly as the two sisters fought.
"How could this have happened?" asked Twilight.
"I'll tell you how." said Rainbow Dash. "Discord. He finally found a way to ensure absolute chaos."
"We've lost." said Twilight, hanging her head. "I've failed you, Princess."
"Now, what kind of talk is that?" asked Applejack. "It sounds like you're giving up."
"We can't give up." said Apple Bloom. "We just can't."
Applejack looked at her sister and smiled.
"I won't give up." said Derpy.
"Me, neither." said Lyra.
Applejack turned back to Twilight.
"Ya see, Twilight? We're all right here with you."
"What's our first move?" asked Rarity.
Twilight thought about it for a minute. "If we're gonna save the princesses, we're gonna need to defeat Discord again."
"So that means..." Rarity started.
"The Elements Of Harmony!" yelled Pinkie Pie.
"Well, where are they?" asked Fluttershy.
Twilight turned back to the castle.
"They're in there." she said.
The group looked down the courtyard at the castle. Lightning and energy blasts repeatedly struck the ground.
Luna fired another bolt. Celestia dodged it and launched a beam of light energy. Luna spun out of the way and circled around her sister like a hawk does to its prey. Celestia fired another beam. This one also missed.
"Come on, sis!" yelled Luna. "We both know I'm the fastest!"
She zipped passed Celestia twice, kicking her in the head both times.
"That's it." said Celestia. "This ens NOW!"
She fired a bolt of light energy at Luna. Luna also launched a dark energy bolt. The two collided and exploded. The light blinded Luna, giving Celestia an opening. She flew though the blinding light and grabbed Luna. She then took off straight for the ground.
"LET ME GO!" yelled Luna.
"ONLY IF YOU STOP THIS!"
"NEVER!"
"THAN YOU LEAVE ME NO CHOICE!"
Twilight looked up and saw the two sisters spiraling towards the ground.
"Pull up." urged Twilight. "Pull up."
Celestia closed her eyes as they impacted the ground. The shock wave knocked Twilight and the others on their sides. The whole front half of the castle crumbled and fell to the ground. Everything went silent. Who won?
