Dark Hearts and Spirits

Twilight slammed the ground with her hoof in anger as they popped out of hyper-space. Damn Trixie! if it hadn't been for her, Dark-Heart would have been dead.  Twilight could feel her magic suppressors heating up as they struggled to contain her raging magic.

"Calm down Twilight, there is still hope" Luna said, grabbing Twilight and shaking her to snap her out of the rage. Twilight's magic continued to flare, causing the Mane 6 to shrink back in fear. Except for Fluttershy.

"I'm angry too but this won't solve anything!" Fluttershy screamed at Twilight while giving her the full force of the Stare. Twilight resisted her hold for a few seconds, before looking down and breathing like Cadence taught her. Twilight's breathing slowly calmed and her magic stopped flaring.

"Thank you, but we have no hope now. Dark-Heart took our best shot and it's doubtful he'll fall for the same trick again" Twilight said, increasing the seal on the magical locks as she did.

"No" Celestia managed to groan as she propped herself up. "Dark-Heart is cocky and foolish and he nearly died from my Solar Flare" Celestia managed to cough out, using up her strength just to talk. "Twilight, if you let all your magic out at once while he's off-guard, that might work" Celestia managed to groan before slipping back into unconsciousness.

"I can't control that, I'd kill you all first" Twilight said, a tear leaving her eye before sinking to the ground sadly.

"We may be able to help you, Princess" Luna said, investigating Twilight's magic with a scan spell. "You just need training to keep your power under control" the nocturnal diarch stated after her analysis.

"Yeah, I'm totally good at training" Rainbow gloated before giving Twilight a good-natured punch to the shoulder. Twilight smiled before steeling herself. Dark-Heart would no doubt be recovering, she would not waste this time on self-pity

"We've got 3 days, I suggest we start improving" Twilight declared, fire in her eyes.

Sweetie Belle, Scootaloo, and Applebloom all looked up to see a smoky figure of a pony, lime green light shining behind her.

"Oh, it has been far too long since I've been let out. Now, what wish do you want?" the Spirit asked, popping it's neck and legs as it stretched.

"A Cutie Mark" Scootaloo squeaked without hesitation while the others nodded rapidly. The Spirit rolled her eyes at their youthful exuberance before opening its pages.

"Just say these words and your wish will come true" the Spirit mumbled from its more cramped position after being back in the book.

"Szkoda dla Cutie znaku" Sweetie Belle read quizzically before her flank burned with green light. A second later, there was a musical note on her flank, a scooter on Scootaloo's flank, and a hammer on Applebloom's flank.

"Now that that's done, you must take vengeance" the Spirit chuckled to the stunned fillies.

"Revenge?" Applebloom mumbled, still in a daze.

"Yes, on Diamond Tiara and Silver Spoon" the Spirit laughed at the fillies. Slowly, the fillies began laughing with the book, a dark laugh that would have made many run in fright. "Not just them, but soon every pony in the world, for not helping you when you needed it" the Spirit managed to say between laughs. Eventually, Sweetie Belle stopped the laughter with a valid suggestion.

"When do we take them out?" Sweetie Belle questioned, horn glowing with dark green magic the same color as Spirit.

"How about we take them down in 3 days? That'll give us time to test out our Cutie Marks" Scootaloo suggested, grinning evilly in a way similar to Spirit.

"Agreed, we've got 3 days, better start improving" Applebloom smirked, not noticing how she looked almost exactly like Spirit in expression.

Dark-Heart sparred at the air, sweat running down his body. He had almost died last time from his lack of skill, it wouldn't happen again. The demon shot several punches at an imaginary foe before settling down for a rest. Dark-Heart sat, thinking hard about Trixie. She was more loyal than any other servant before but was that a good thing? Dark-Heart remembered Discord's mocking words about him loving her and how he had sent her away so she wouldn't get hurt in that fight. He told himself that it was just so he could keep a valuable servant but was that true? He looked at the wounds that still covered his body, remembering how he had felt when Trixie had saved his life. Such caring being shown to anyone, even him, went up against his goal to destroy all love and caring from the world. If that was the case, why did he feel good when she did that?

Trixie meanwhile, decided to meditate for the first time in her life, a common practice done by unicorns to focus magic. Trixie still struggled with what to do now. She had failed to beat Twilight again but Luna's mind invasion had shaken her opinion on whether or not to kill Twilight. Another question she needed to answer was what should she do with Dark-Heart? The demon had given her all of her new power but he'd also stricken her mind with thoughts of killing ponies. Even then, she had saved him. What was wrong with her?!

"Don't look so glum Trixie, we have 3 days to improve ourselves" Dark-Heart smirked as he practiced shooting off magic at the sky. Trixie shook herself and got out of meditation, her mind clear. She would defeat Twilight, but she would do it legitimately, not with help.

"I've got three days to train, best make use out of it" Trixie snarled before launching into a sparring match with Dark-Heart.
