The next morning, the yacht reached land and leaped off the boat. Their majesties and their dragons leaped off of the yacht and found themselves in a large area with volcano's and lava pits all around. "The Dragon Lands." Celesto said. He took out the map and it glowed. Zooming in on the dragon lands, a blue line appeared and made a path on the map as well as the ground. "Looks like we have to follow it." Celestia said. Celesto nodded and they followed the blue path through the Dragon Lands and stopped at the base of a volcano. They walked inside and came out in a large chamber. In the middle was a large pool of lava and a bridge that connected the two side of the chamber.

At the other side of the chamber was a shrine with a gem floating in the center with a mystical glow to it. "That's the gem." Celestia confirmed. "Let's go."

But before they could begin to cross the bridge, "Not so fast!" three magic beam came and almost hit their majesties if they haven't jumped back. That's when Chrysalis, Nightmare Moon and King Sombra appeared before them. "You two aren't getting that gem." Nightmare Moon claimed. Chrysalis whistled and her changeling, shadowbolts and bat ponies came and surrounded their majesties and their dragon. "If you know what's good for you, you both will come quietly to the dungeons of New Canterlot." Chrysalis said.

Their majesties growled, but they knew they couldn't fight all these minions and their leaders by themselves. The minions appraoached them, ready to captured them. Their majesties stood back-to-back, seeing no other way out of this but to fight.

Suddenly....

"Leave our friends alone!" a voice cried.

"What?" the three leaders cried. Everyone turned and saw Shadow, Comet, Blaze, Sapphire and her Night Fury and the Changeling Resistance all standing in the entrance to the chamber. "Let them go!" Shadow cried.

"And their dragon too." Comet added. Their majesties smiled at each other. Their friends had come all this way to help them save their universe. Nightmare Moon laughed, "You pests don't stand a chance against us. Take the ponies!" The shadowbolts and bat ponies lunged for their majesties but Dusk and Dawn swatted them all away and Sapphire's Night Fury blasted them with his plasma blast. "Gp for the gem, We'll handle them!" Alternate Starla said.

Their majesties nodded and made a beeline for the gem, crossing the bridge quickly. Their friends were fighting against their leaders minions and winning. The Changeling resistance swatted the changeling with their spears, Shadow blasted the shadowbolts with her magic while Blaze and Comet punched and kicked them. Sapphire also blasted the minions with her magic and her Night Fury fired his plasma blasts at them. Their majesties made it to the other side of the chamber and approached the gem when Nightmare Moon and King Sombra landed in front of them. "You two aren't getting away." Nightmare Moon hissed.

They blasted their majesties but they created a shield around them, deflecting the blast. Sombra growled and lunged for Grand Ruler but Dawn grabbed his by his cape and threw him to the other side of the chamber, knocking him into some of the shadowbolts. Dusk and Dawn then blasted Nightmare Moon with their fire, sending her flying, and giving their riders a clear shot to the gem. They both grabbed it and immediately it glowed brightly. The friends and minions stopped and stared at them. The gem spun around and around as it glowed brighter and brighter. "No." Sombra said.

And the gem sent out a large, powerful shockkwave, destroying the minions. "NOOOOO!" the three leaders cried as the magic from the gem destroyed them as well. The magic shot out of the volcano and spread throughout United Equestria, restoring it to it's original state and everything turned white.

Their majesties slowly awoke to find their two headed dragon staring at them. Dusk and Dawn licked their owners, happy they were awake. "Hehe, it's good to see you both too." Celestia said.

They both sat up and found themselves in bed. They got up and went outside to find all their friends outside, all with happy smiles on their faces. "So our heroes are awake now." Alternate Lightning said.

"Thanks for saving out world." Alternate Starla praised.

"Your welcome." Grand Ruler said. "It was out pleasure."

Fluttershy came up to them with the gem. "Now that you've helped us save our world, you can go back to your dimension... hopefully."

Celestia took the gem in her hands,

"We won't forget you,
Your heroics were true." Rhymey said.

"Remember, you may have to go through multiple dimensions to get back to your own." Lightning added.

"Right." Grand Ruler said. The gem glowed in Celestia's hands and Grand Ruler touched her shoulder and their dragons touched their shoulders and all at once the three of them glowed and vanished in bright flash of white.

Author's Note

Any suggestions for alternate dimensions are welcome.

I think I may do one arc with them in the Yo-Kai dimension.
