The Phantom Pegasus

One long story and an explanation about a half ghost pony and his friends, Danny sat (in ghost form) with his friends before Celestia. She was shocked and silent for awhile. Finally she smiled. "While I can't say I've ever heard of anything like this is my lifetime, it's all the more interesting- and you, Danny, are one of the most unusual ponies I've ever met. Can you describe the ghost who you said sent you here?"

"Yeah," Sam said, "She was glowing green and had a weird black cape with a hood. She also had a necklace with a red and yellow gem in it."

Celestia's eyes widened. "A...a red and yellow gem, you say?"

"Yes..." Tucker said, wondering where this was going. Celestia sighed mournfully and shook her head. Danny changed back to normal, waiting for the story.

"There's a regrettable tale behind it. There was a few years ago a unicorn named Pravus. She was a lady of nobility and had good magic skills and was pretty, but that wasn't enough for her. She wanted to find a gem only heard of in legends that could teleport between worlds- she suggested that Equestria could use it to open trade routes between worlds, but everypony thought her a sandwich short of a picnic for even thinking she could find such a thing. Her heart was in the right place, but she began to become insane from all the denial she would receive from ponies who said there was no such thing. Her mane even began to gray from the intensity and stress she put on herself to prove it to everypony."

Everyone was waiting for the rest of the story. Celestia took a breath. "And eventually she left to find it to prove it to everypony- not getting any help from anypony on her adventure. She was never heard from again. That may have been her downfall- maybe something happened and she had no one to help her. Anyhow, the gem was red and yellow? Did it have a swirled texture in color?"

"Yeah. And it glowed when she used it." Danny answered. He shrugged. "We're not completely sure why she got rid of us and threw us here, but it can't be good. Especially since we're the heroes who prevent those bad things from happening. Specifically, it's probable she wanted us out of the picture since we could put a dent in her plans."

Everypony was dead silent- Twilight Sparkle spoke up. "This means it could be trouble for all of us- not just your world or the Ghost Zone you mentioned, but Equestria. I doubt she's just not gonna do anything to our world as well."

"Of course, Twilight Sparkle. I just never imagined Lady Pravus would be evil...or get so insane to be as such. If we're going to stop her, we're going to need to find a way into that world. With enough unicorn magic, it may be possible. But-"

There was a flash of light that blinded everyone for a split second, some shouts, and then everypony turned to see what happened. A gigantic orange unicorn and a smaller, teal pegasus pony lay sprawled on the floor- both were groaning and trying to shake their heads free of confusion and a thumping headache that was starting to form. Pinkie Pie squealed.

"Yay! New ponies!" she said, trotting up to the couple. The orange one fully came to consciousness first, and nearly jumped back at seeing a pink pony right in front of him. Danny finally got a glimpse at the cutie mark- a ghost- and realized who the ponies were, his eyes getting wider seeing the gem he had just described under the teal pony's hoof.

"Mom? Dad?"

Both ponies snapped their heads up when they heard that familiar voice. They gasped. "Danny!"

At Fentonworks, Jack had tied down the unconscious unicorn pony to a table for questioning. Maddie stopped at gazed at the necklace and remembered that that was the thing that the kids described. She carefully took it off and examined it. It was beautiful, but it seemed harmless.

They waited for a bit, and eventually the ghost woke up, dazed and baffled. Her eyes caught onto the two ghost hunters and then scowled. "Who are you? What is this nonsense?" she asked. Jack was the first to speak up.

"We're ghost hunters. You picked the wrong kids to send to a different world." he said, fury growing in him. She rolled her eyes.

"I don't know how you managed to hear from them, but your attempt to stop me is hopeless." Her horn glowed and off came the ropes that previously held her down. Maddie shoved the necklace in her pocket and she and her husband held out their ectoguns and decided to not hesitate to make a shot at her. The shots managed to hit her and knocked her back. She darted her head up and her horn glowed again. She pulled the ectoguns out of the hunters' hands and tossed them aside.

She was about to use her necklace on them when the unicorn realized something- it was missing. Pravus looked up, enraged. "Where is my necklace? It has my precious gem on it. Return it now!" she demanded, approaching the humans. Maddie defiantly shook her head.

"Never." She gripped onto her husband's hand, expecting the worst. Inside, she was wishing she and Jack could be teleported somewhere else, somewhere safer so they could still stop the ghost before them.

The gem in her pocket began to glow, and before either could react, a portal formed under their feet and they fell through. Pravus gasped in horror as the portal disappeared. "No- no!They have it! They have that gem with them! How am I going to..." She paused. "They'll return eventually, Pravus. They have to. And their daughter is still here...and this could give me time to build up my army again without any sort of interruption. Yes, indeed. This could be useful..."

Upstairs, the door opened. Jazz looked around, wondering why there was silence. "Hello? Anyone-" She was cut off when the ghost her parents had been hunting appeared before her with a twisted smile. Jazz fainted from shock and fear. Pravus laughed.

"That was easy. Now I have a hostage. Seems like everything is going my way today!"
