Chapter 6- Derailed and Decomissioned.

Firestorm was relaxing in a leisure car, when rainbow dash came and sat next to him. "Sorry about yesterday storm" he smiled in his ever calm manner. "It's alright rainbow, I was known to be a bit of a Casanova, and not the most successful lover mind" Rainbow laughed, (Even royalty can be a bit dim, it's cute) Rainbow thought. "Thanks for this stormy, you know... Despite you turned me down, you deserve a marefriend, a special one" She put her forehoof on his shoulder, and he hugged her with his wing.

The train began rattling and swaying side to side, firestorm got concerned and ran to find the others. "Were derailed sir! And there is something out there that is smashing parts of the train!" the conductor yelled at him

"Diablo... Midnight metropolis is north of here, RUN!" the 6 ponies and spike began running for the City always enveloped in nighttime. Storm stepped out and stood a few metres from Diablo. "Trying to seal me away with the elements Fire? You might have a problem without this" Diablo pointed to something on the dark pony's neck, The Golden bond of Light. Storms horn flared, his hornpiece reflecting what it represented. And then, there was the explosion.

Rainbow dash heard the loud blast and shot up, Firestorm was losing the fight, she began rising up in the air, only to come crashing down at speeds never achieved by any other pony, and then she cracked a sonic rainboom, the sky burst into a full colour spectrum as the cyan Pegasus screamed into Diablo, differentiated by a black coat, and a red mane, whereas firestorm had a red coat and a black mane. Rainbow straightened out and went crashing into Diablo, cutting off his stream of magic, and hitting her with it, the necklace fell off and Diablo, knowing he'd lose, shot off with a flash. "Oh my god, Rainbow!" she came to and saw firestorm clutching her in his arms, she gave a weak smile, and shut her eyes. he felt for a pulse, and got a strong heartbeat, he held her tight, as the other ponies came round him. "I'll get her to Heavens pass, best hospital in equestria, you six need to get to midnight metropolis, Luna will be expecting you"

"Okay storm, take care of her" AJ said to him, he nodded, flipped up his hood, tied rainbow to his back and got ready to leave but then Fluttershy stopped him. "Mr firestorm? Look at the necklace Diablo dropped" He smiled at Fluttershy and put it on, it gained a bright luster, making the gems light up and shine like stars. The ponies awed at the gems on it, and firestorm felt stronger than ever, "Now all we need are those wing blades and I can banish him, we're so close, Good luck guys" they waved goodbye as he charged his horn, and disappeared in a burst of flames, with that, the ponies walked to midnight metropolis.

Chapter 8- Heavens Passing

Meanwhile at Heavens Pass Hospital, Firestorm arrived at the reception, hood down with an unconscious rainbow dash on his back, her breathing assured him she was alive. "My friend was assaulted, and is really hurt, she is unconscious but breathing, get her a ward, and patch up her wing and left hoof, she's broken both" Nurses placed her gently on a bed and took her to her wing. Firestorm went with her until she was sleeping on her bed. "Thanks for coming on such short notice Doctor Whooves, and thank you as well Ditzy, she'd be glad to have your company"

"This looks like an arcane bolt to me, and a strong one at that, that explains the hoof, but what about the wing?"

"Sonic Rainboom Doctor"

"I see, speeds like that would do that, she'll need rest, but feel free to stay with her if you wish" Doctor Whooves said to Firestorm, Ditzy looked at Whooves and then smiled at Firestorm and left the room, the Alicorn went up to the bed and held rainbows hoof. "I didn't mean for this to happen rainbow, I didn't expect you to attack Diablo like that and put us one step closer to saving equestria, I cannot thank you enough, and as I am now in your debt, I will stay with you and take care of you till you are in good health" he kissed her on the forehead and pulled up a chair and sat next to her and waited.

As the remainder of the group came up to the mane street that ran straight through the city, it seemed relatively unaffected by the cataclysm which came as a surprise to the ponies, spike belched a letter from Storm. "Rainbow was really hurt by Diablo, but Doctor Whooves said she'd be fine, she just needs rest, storm said he would keep an eye on her till she's okay again" twilight read, wishing the best for their friends. Rarity was dazzled by what everypony was wearing in the city, to show off, she clapped her forehoofs and her hoofs lit up, everypony saw the fires, twilight and the others did the same, they looked like quad-pedal Phoenixes, the crowd was cheering and screaming to see the flaming ponies, it was primarily to attract Luna's attention, rarity just wanted everyponys attention, but sure enough, Luna came into the city square, everyone bowed, the other six stood proud. "I presume firestorm sent you?"

"Yes your majesty, we came for the wing blades, to banish Diablo" Twilight said firmly

"WOW! Look at all the colours and all the-"

"Not now pinkie..." AJ hushed the pink earth pony.

"How do I know, that firestorm can use them to SAVE equestria, and not destroy it?"

"Luna, his sentence is over, the real firestorm is at peace, and he wouldn't harm Anypony except for Diablo"

"Granted, they will remain in his care?" And twilight nodded in response, spike sent a letter to Storm telling him to collect the wing blades. He arrived in a matter of minutes. He greeted Luna with a sisterly hug, "Hello little sister, how are you keeping?"

"Very well firestorm, Here are the wing blades of Darkness, as promised" He reached out for them, when there was a loud blast in the sky, and Diablo swept past and swiped the wing blades. "I'll hang onto these I think" He smirked as he charged his horn to leave, only to be sent crashing down by royal arcane artillery, firestorm stepped forward, and poised his magic ready, as did Diablo. Firestorm shot first, ensnaring Diablo in a grip, and choking him, he writhed and shouted, his horn blazed and sent a large burst out, knocking off firestorms concentration, the choke broke off and went straight into firestorm, afterwards disappeared in a burst of fire, leaving the blades behind accidentally. Firestorm crashed to his knees, there was a large scar across his chest, and was bleeding heavily. "Storm! We need to get you to a hospital now!"

"No" He said placing on the blades, the entire set was complete, it glew like the sun." I can finish him now, we head to canterlots ruins, I can perform the Burst of Purity"

"You're too weak" Fluttershy said, but storm got up and primed his horn, magic was now effortless. "We go now."

"Good luck big brother" Luna hugged him, and he teleported them to canterlots ruins, for the final showdown
