Light chuckled as she descended and landed in-front of her mother. "What's wrong mother, surprised to see me?" she asked once she had landed
"I'm more surprised to see the race you took on." Harmony said.
"Oh, well I would love to talk, but we really should get going to face the darkness." there was an odd tone to Light's voice when she spoke about the Element of Darkness.
The bearers nodded and left with Light to face the current evil of the land.

Hidden in a small castle deep within a forest of dead trees and evil magic, was a Pegasus mare. Her once orange coat was as black as night, her mane and tail were now bright yellow and seemed to be made of electricity, her eyes were glowing red, and her teeth had become sharp and pointed. Dark Mist was in the center of a large black shield, a black necklace around her neck with two blood-red interlocking crescents embedded in it.
The door to her base suddenly exploded as a pony walked in, her flowing mane and tail seeming extremely erratic.
"And you are?" Dark Mist asked, believing she was too strong for this pony.
"I am the light." the pony said.
"That doesn't answer my question, oh well." Dark Mist waved her hoof dismissively and a shadowy energy exploded from her to attack the pony, the impact filled the room with smoke. Dark Mist didn't even cough at the smoke as it slowly dispelled... only to reveal the pony she had attacked to be in a shield that matched her mane and tail in color and instability. Dark Mist didn't waste time as she shot in the air and expanded her shield. this mortal can't possibly break my shields she thought as the pony seemed to prepare herself to attack.
The gold-coated pony shot forward as Dark Mist caught a glimpse of the element bearers behind her. The pony hit Dark Mist's shield, and it shattered, sending both ponies spiraling.

Light stood over Dark Mist with a smile that radiated almost every emotion there was. Her mane and tail had somehow calmed down by the time her and her polar-opposite had landed. The gold mare jumped off Mist as she walked over to a table and sat with an evil smile.
"Now then, I believe introductions are in order. My name is Light, I'm the newest daughter of Harmony and the true Element of Light." Light said.
Mist growled as she stood up. "How could you shatter my shield?" she asked angrily.
"The same way you cancelled out my power when I impacted you. You are darkness and I am light. When we're touching each other, we're limited to our default magics. I can't access my Light and White magic and you can't access your Dark and Black Magic. Now come on." Light teleported her and Mist out into an open field, the element bearers were sitting on the side, also having been teleported.
Light took flight as Harmony magic swirled around her wings. She was soon followed by Dark Mist, who looked rather angry.
"You know Misty, none of you Dark Magic or Black Magic attacks will really effect me, that just leaves you with your natural Pegasus Magic." Light said with a grin.
Mist was rather angry with the nickname and launched herself at Light, who simply waved her hoof dismissively and sent Mist flying. Mist groaned at the impact and slowly stood back up, channeling a lot more magic than necessary before sending a powerful bolt of lightning towards her opponent, who shielded it with ease. This only angered Mist more as she attacked head on and managed to slam into Light, once more sending them spiraling.
Light kicked off Mist and caught herself mid-fall. The momentary distraction, however, was enough for Mist to hit her with a powerful blast of pure Pegasus Magic. Light eventually hit a building and got up, flying right back to Dark Mist.
Dark Mist began sending powerful storms towards Light as the young element countered with blasts of Harmony Magic. After about three minutes of neither getting a hit, they both sent out strong waves of their respective magic. When the Dark and Light Magic contacted, they exploded. Both Light and her counterpart were sent flying, the magical explosion holding enough power to badly burn both of them.
Light got up slowly, followed by Mist, who was grinning madly. Light, deciding that holding back her most powerful magics wouldn't get her anywhere, sent out a bolt of Light Magic. In response, Mist countered with a dark magic bolt before throwing up a shield. Again the two opposing magics exploded, and again Light was sent into the ground. As the young element stood, she noted how much more power had been behind the explosion.
The combatants met in mid-air, stopping in a hover. Mist was charging her magic to the fullest while Light was simply hovering their calmly. Alone, she wouldn't be able to face the darkness, but she wasn't exactly alone.
Closing her eyes, Light reached across the plane of magic and to her siblings, asking for their strength, which they gave. Light repeated this for her mother and then spoke to the bearers.
"Do you trust me to the fullest?" she asked.
"Light, we trust you with our lives." Cool Breeze said.
Light reached out and tapped into the six bearer's power, then reached into herself, into her very soul.
Light's soul was a pulsing white orb with black tendrils wrapped around it and several rainbow colored straps holding it in place. She used her magic and took hold of the straps, what she was about to do was something nopony with half a mind would dare to do without a good reason. Light gave a strong pull, and the straps snapped causing her soul to surge with the power it was meant to hold back.
Light snapped open her eyes, her mane and tail becoming erratic and almost fire like, her pupils and irises become swirling pools of rainbow, and the Harmony magic around her wings intensifying tenfold. In short, she was terrifying.
Mist finely unleashed her power, only for the shear force of Light's own to swallow the power whole. After dispelling any lingering Dark and Black Magic, Light sent a powerful wave of magical energy right at the Element of Darkness, causing her to crash into the ground.

As the smoke cleared and Light landed. Dark Mist was revealed, but her original colors had returned and it seemed the Element of Darkness was badly cracked.
"Mark my word Spirit of Harmony, I will return." a dark voice spoke from around the necklace before it shattered.
Dark Mist had tears in her eyes as she looked up at Light. "Than you." she whispered.
"What was your name?" Light asked calmly, to which Dark Mist shook her head.
"I can't remember, I just remember what I used when I put that necklace on." Light nodded at that and turned to the bearers, who were all staring at here.
"Gee Light, was it really that necessary to use so much magic at once?" Star Nexus asked with a smirk.
"Nope, but I figured that I shouldn't hold back on my first day of existence." Light said.
"Wow, you've got a lot of magic." Silver Mist said.
"Not really, that was about average for anypony, I'm just the only pony willing to perform the necessary action to do it."
"What would that be?"
"Sever the binds around your soul that hold back most of your magic."
Silver shivered at the mere concept of that. Any well learned Unicorn could tell you that doing that was eight times more dangerous than casting a black magic spell.
"Hey don't worry, the binds reform after a while." Light said as she flew over and rested a hoof on silver's shoulder.
The group spent the next two hours just talking and trying to calm Dark Mist down.
