Leaving her students behind, Twilight followed Dr. Strange and soon found herself in the throne room where the royal sisters were waiting.

"I got your scroll, Celestia," said Twilight walking up to them. "What's going on?"

"The Elements of Harmony have been corrupted," replied Celestia worriedly causing Twilight to gasp in shock.

"What? How?" cried Twilight, stepping back in shock. "How can they be corrupted?"

"Colonel Rhodes inspected the tree of harmony after Changelings were found nearby," explained Luna, much to Twilight's shock. The Princess of Friendship could only just stand in front of her mentors with a look of shock on her face. In her mind, she couldn't figure out how the Elements of Harmony could have been corrupted.

Then, a thought crossed her mind.

"Wait a minute," she gasped. "I do remember something. It was when my friends and I were on our camping trip in the Everfree."

"Who goes camping in the woods?" remarked Dr. Strange.

"Uh, we do," replied Twilight, looking back at him, before looking back towards Celestia and Luna. "Anyways, we noticed that the tree of harmony was frequently changing colors and…"

Twilight then suddenly stopped again, this time for a much longer period of time.

"Changing colors," she gasped. "My friends…they were being themselves."

"Um, I don't know what it is you are talking about, Twilight," stammered Celestia.

"When we were in the Everfree, I thought all my friends were just being in a bad mood because I was pushing them to attend this retreat," said Twilight. "But, they were being themselves and the ponies I thought were them were…"

A hushed voice came through Twilight's lips with what she said next.

"…clones. They were clones of us. But who would want to create clones…? Chrysalis, Chrysalis did this to us! I should have known! The photographer, the pictures, the hairs she pulled out of our manes and tails, it all makes perfect sense now. She was the one behind all of this, she was the one who ruined the camping trip, not me!"

"Then Chrysalis was the one who corrupted the tree," cried Luna to Celestia. "She must have tried to take the Elements of Harmony for herself in an effort to avenge her defeat by Starlight Glimmer!"

"And now, because of her, Grogar can easily take them," added Celestia. "It shouldn't just be our Alicorn Magic we should be worried about right now, but also the Tree of Harmony itself!"

"We can defend the Tree of Harmony as best we can," said Dr. Strange to the Princesses. "But, we are going to need additional help."

No sooner did Dr. Strange say that at that very moment, the doors opened and Cadence, Shining Armor and Tempest Shadow came into the throne room with the Guardians of the Galaxy following close behind.

"Tempest," gasped Twilight running over to embrace her reformed enemy. "What are you doing here?"

"We've come to help fight," answered Tempest.

"But, what about the Crystal Empire, Cadence?" asked Luna. "It's left unguarded!"

"As long as the Crystal Heart is activated, it will be protected, Aunt Luna," replied Cadence. "Flurry Heart is staying with Sunburst where she will be safe."

"Heh, nice place you got here," remarked Rocket, catching the attention of Princess Luna. "Oh, uh, name's Rocket…leader of the morons."

But the raccoon was met with a small kick from Quill followed by a brief and blank stare.

"You'll have to excuse him," chuckled Quill. "I'm Peter Quill, leader of the Guardians of the Galaxy. You can also call me Star-Lord. This is Gamora, Drax, Mantis and Groot, my fellow guardians."

"I am Groot."

"I am Princess Celestia," said Celestia, awkwardly looking at the humanoid tree creature before pulling herself together and focusing on the task at hand. "But we can further introduce ourselves later. Right now, we have to prepare for Grogar's arrival."

…

Meanwhile, down in the depths of Hell, the cloaked figure approached Loki's cell once Satan had disappeared from view.

"Who are you?" Loki asked. "And what do you want with me?"

"Ask me who I was," answered the cloaked figure.

"All right, who were you then?"

"In life, I was your brother," answered the cloaked figure, removing its hood to reveal a man with short brown hair and a brown average length beard. "Thor, king of Asgard."

Loki gasped at the sight of his brother. The last time they were together was when Thanos had attacked them and destroyed their ship.

"Brother," gasped Loki. "I never thought I would see you again. What are you doing here?"

"I want to know what Grogar is planning, Loki," replied Thor. "I saw him. He was here, not too long ago. What is he planning?"

"Since…since you asked so nicely, Thor," Loki replied. "Grogar has been coming here to free several spirits, including Ebony Maw and Proxima Midnight, two of Thanos' children. He just came back to free the souls of six evil ponies."

Thor took in this information and realized more and more that Grogar had indeed returned.

"He's a danger, brother. Even more so than Thanos."

"Did he say anything else, Loki?"

"No, he didn't. But, you must stop him. It's too late for me, but it's not too late for you to stop him."

Without acknowledging his brother's words, Thor activated his hammer, Stormbreaker, and with a flash of lightning disappeared from hell and soon found himself back in Equestria. However, rather than ending up back in Canterlot, he found himself in the former location of Ponhenge. The skies overhead were darkening with black clouds and rumbles of thunder were heard. Just then, an older looking pony with a long white beard and wearing a blue cloak and hat appeared from the bushes.

"Are you Thor, King of Asgard?" he asked, catching Thor's attention. "And the one who helped my pupils overthrow Emperor Grogar and his kingdom Tambeleon?"

"Yes, I am he," Thor replied stepping up to the pony. "I am Thor, King of Asgard."

"I am Starswirl the Bearded and your timing couldn't have come better."

Thor could only stare at Starswirl, almost as if he knew what was coming to him.

…

Meanwhile, Julia and Tony were going over their interview with Starlight Glimmer when a Stark employee pony came in.

"This just came in from Twilight Sparkle's school of friendship," he said, handing Julia a message. "It's says your daughter was evacuated along with the rest of the school."

Julia could only sigh heavily and fidget with her golden pearl necklace.

"Where is she going to?"

"Not sure yet."

"As soon as you find out where she is going, tell me, is that understood?"

Acknowledging, the pony employee left.

"At least she will be safe, Tony," said Julia, tears forming in her eyes as she sat back down and buried her face in her hands.

"That's all that matters, Julia," remarked Tony. "And you will see her again, I promise you."

But Tony's words didn't convince Julia that things were going to be all right. For she had a premediated fear that something was going to happen that would take her daughter away from her forever. What's more, Julia wasn't the only one. Every single family in Equestria was suffering the anxieties of Grogar's growing threats and they weren't going away any time soon.
