Earlier at the entrance of Tartarus, Mizuki, Byron and Jay had gathered on the orders of their leader, they weren't allowed to enter and had to wait until he arrived. "Where is that guy? What is taking him so long!?", Byron complained gaining a death glare from Mizuki. "Show some respect, without him you would be here.", she scolded him. "Indeed, I would have been in my study doing something useful. I bet our Dark Lord is in his study, talking to... whatever it is he's talking too.", Byron said as he got in another argument with Mizuki. Jay couldn't help but sigh, why couldn't those two just get along? "Stop it both of you!", he shouted moving between them, "Just fuck each other already!".
Before either of them could respond, a dark blue cloud rushed from the sky, coming together on the ground before them as it took the form of their boss. "I see you three are being lively.", Marc said as the three stood straight. With a flick of his wrist two scrolls appeared, one floated to Byron and the other to Jay. "These are your mission for today. You might be wondering why I called you here. Well for one it's convenient for me. Unfortunately the weapon I'm looking for isn't in the bowls of Tartarus. But fortunately, the key to unlocking its location can be found at the bottom of this dungeon.", he explained gaining a nod from the members of his inner circle.
Mizuki smirked, know she knew why he didn't gave her a mission, he wanted her to go and, "That's why I will personally go and retrieve it. Mizu, I want you to accompany Jayden over here to Arendell. If our information is correct, Arendell is ruled by a very powerful Cyromancer.". Before Mizuki could protest, "You know your missions, now go.", he commanded as the three disappeared into dark smoke. Turning his attention to the unremarkable rock formation, with a burst of telekinesis, the rock split open, revealing a spiral staircase.
Meanwhile in a ally not far from Ponyville's Main Square, a white portal opens. Soon a young woman with a tanned skin, light blue eyes, a lithe muscular build. Her dark brown hair was tied in a high pony tail. "It seems I'm not in Republic City anymore...", she said as she walked out of the ally and into the Main Square. "That's new.", she noted to her self as she saw the ponies walking around. Scootaloo accidentally ran into her. "Oh, sorry. I should have been looking where I walked.", Scootaloo explained, surprising the human girl. "Aren't you afraid?", she asked, surprised that the young filly wasn't scared of a strange being. "Should I be?" she tilted her head, "A friend of Ser Skywalker can't be that bad.".
"Ser Skywalker? You know Jason?", she said gaining a nod from the filly. "Everybody knows Ser Skywalker! That's him.", the filly said pointing towards a large statue of Skywalker holding the planet in on hand high above his head. "Well, at least I have one friend in this strange new world.", the girl commented.
After traveling down the staircase, Marc found himself staring into six eyes, three sets of razor sharp teeth and three noses. "Cerberus? Perhaps I should make you Mizu's pet.", Marc said sarcastically as the beast charged at him. Conjuring his Keyblade to his hand, "Will this be challenging?", he question himself as Cerberus attacks with its teeth from the middle. While Marc easily deflects the attack making the guardian recoil, the force of the blow knocks Cerberus through a large rock in the area. As Cerberus recovers, Marc begins to unleash a fierce barrage against it, makes a particularly powerful swing and sends Cerberus reeling through the air. Marc opens a dark portal, sending Cerberus somewhere else.
"An empty victory," Marc said to himself, as he made his way through the gates. Marc had made his way into the central chamber of Tartarus, from here he could get anywhere into this hell prison. "This is what they call security? I presume they only care about prisoners leaving this hell hole.", he noted as he took another spiral stairs further down.
"How long has it been since we saved Equestria? To think we failed after we fought so hard. They should have looked up to us as heroes, be inspired to be like us. Instead they treated us like monster, a danger to the human race. Someone had to take a stand, someone had to protect us.", Marc said to himself as he found himself flashing back to those days.
At the war room, Marc, Celestia, Lily and Celestia's Royal Guard Captain were standing over a war table discussing which strategy would best work at defending against The Outsiders. "We will draw them into this valley here, and on your signal both our armies will charge and trapping them. This strategy will be our path to victory.", the Royal Guard Captain said. Celestia trusted her commanders judgement but to her surprise, the young Keyblade Knight had a objection, "The key to strategy... is not to choose a path to victory, but to choose so that all paths lead to a victory.", he said as he proposed multiple ways to ensure their victory with minimal lost of life for their side.
As he relayed the orders to the commanders, Marc noticed Lily talking with Celestia to the side. Using his advanced hearing, he picked up at what the two ladies were discussing.
"You think we have a chance of winning, Lady Skywalker?", the sun ruler asked as the young woman nodded. "Yes, your highness. With the combined strength of our armies and with Marc leading us, the outsiders are finished.", Lily said with the utmost confidence. Celestia gave her a warm smile as the two talking about earth. It seem princess of the sun had taken a liking to the young Superius. "Is something the matter?" the ruler of the sun asked her, seeing the worry in her eyes. "I'll be honest with you, your highness. I had another reason to come to Equestria. The Outsiders have made an alliance with these weird, bug things. They have taken my mother..." she explained but Celestia interrupted her.
"Then what are you doing here? Go safe her!", The sun princess commanded making the young woman in front of her confused. "Indeed, go find your mother. We'll make sure she has a victory party to come home to.", Marc told her as he approach the two. Lily gave the two a grateful smile before running off, following in the direction her Sense was pulling her to.
"She is special isn't she.", Celestia said as the young knight couldn't help but agree, there wasn't a woman he could possible love more. "I hope they will be okay.". Upon the puzzling look from her new ally she explained, "Don't you know? Lily is with child.".
Marc was brought out of trip down memory lane as he stood in front of a large stone door, four chains were held together by a lock, they had hopped that who ever was locked here would never be set free again. Stretching out his hand, in a flash of light his keyblade, the Morning Star, a small beam of light shot out of the tip into the lock. After a metal click, the lock disappeared, the chains dropping on the floor with a loud thud. Inside the vault like prison, he saw a very frail, with muted colors and roughly at the height of a normal pony, chained to the wall.
"Lord Tirek, I presume?", Marc asked as his eyes flashed blue menacingly under his hood.
The frail centaur turning his head as he let out a raspy chuckle, "Its been some time since I have seen another face around here.", Tirek said as he studied his visitor. "I have come to relieve you from your torment.", with another flash, and Tirek's chains disappeared setting the centaur free. "We do not have much time before the guardians arrive, now lets go.", Marc commanded, he didn't need to tell that the centaur twice as Tirek quickly followed him. The exit of his prison was unfortunately blocked by a small army of the Guardians, shadows given life. All those years in Tartarus had left Tirek weakened, forcing him to rely on this mysterious stranger to fight them for him. "Could this be challenging?", Marc muttered to himself, he kept asking this question though he knew there was only one who had ever fought him to a draw, and that was only because she had given birth moments before their final battle.
Meanwhile over back over at the Beach Resort, Celestia woke up with a pounding headache. "Ow... Damn, what did I do last night?", the princess asked herself suddenly remembering the 'Never Have I Ever' game they played. She tried to stand up to get a shower but gravity seemed to feel a hundred times stronger than normal, what didn't help was that her legs felt like jello as she crashed down to the ground with a loud thud. Suddenly, she could hear loud foot steps coming up. "Ah, sleeping beauty has woken up!", the sarcastic voice of Griffifth made his way into her ears as she felt two strong arms lifting her up easily. "Ease up, you over did it with the cider yesterday.", Griffifth told her as he gently sits her down on the edge of the bed.
Celestia nod weakly, rub her face, looking over her room mate, who himself seemed like he didn't have much sleep. "Griffifth... You look... Look a little pale...", she said as the blond rolled his eyes. "Well, that's what happens when you spend up all night holding back your room mates hair when she throws up.", he informed her with a annoyed tone to his voice. "Anyways, the rest as left to go to that amusement park. Didn't want to leave you alone so...". He quickly stood up, making his way to the bathroom. If Celestia didn't knew better, she could have sworn that Griffifth had a faint blush on his face.
The rest of the Harmonic Heroes meanwhile had arrived at the amusement park, where there were tons of rides and other attractions to keep them occupied for the rest of the day. This was their last day before they would head back to Ponyville, so they had vowed to have as much fun as possible. Phoenix suggested to split up in groups but none was having that. A certain yellow Pegasus was slightly disappointed at this, "Aw... I was hoping to be alone with Skywalker. We would go on the Ferris Wheel and get stuck on the top, or some other romantic thing that happens at an amusement parks.", she thought to herself not noticing that they were now standing in line for the biggest, fastest roller coaster in the entire park.
Snapping out of her thought, Fluttershy realized where they were standing, she was deathly afraid of roller coasters. "The Goliath?" she said nervously. "You're not scared, are you?", Skywalker asked, turning his head to the shy mare. He had no problem with going on the ride, but Fluttershy obviously did. Knowing it would do no good to lie to him, "Maybe a little…", she admitted.
"You don't have to go if...", he started but Fluttershy shook her head. "It's just a ride. But I would feel better if you sat next to me.", she added with a blush, making Skywalker nod. She was hoping there was a long waiting line, but she momentarily forgot about Skywalker status as Knight Of The Wind and everybody moved out of the way for his.
"So there are some perks of being friends with Skywalker.", McGrath said as the group walked to the front of the line, where the roller coaster was waiting for them. Skywalker guided Fluttershy to sit in the front car. At first, she was ready to object, but Skywalker told her that riding in the front car is actually a smoother ride than riding in the back.
"If it makes you feel any better," Skywalker said to her as the group all got strapped in, "you can hold my hand.".
Fluttershy's hoof delicately gripping his hand as the ride operator pulls the lever and lets the coaster go. Unlike most roller coasters, which go up a large hill, then make a steep fall, this one made a steep fall right off the bat, sending the gang rushing down at an incredibly high speed. It's at this point where Fluttershy's grip on his hand increases one hundredfold.
Back at Tartarus, Marc and Tirek were making their way back to the surface. Marc had indeed been right, even after the Guardians had summoned reinforcement, they still didn't stood a chance as one by one they fell to Morning Star.
"That's an... interesting sword your carrying." Tirek noted, looking at mysterious weapon his companion wielded against the guardians. Marc looked at him from under his hood, "Its a keyblade.", he informed him as the duo made their way towards the exit. "I see, so that's a keyblade... And I suppose he must be its chosen wielder. I wonder if it will change its mind, once I'm back at full power.", Tirek thought to himself as the duo stepped into the daylight, darkness soon took Tirek as he teleported himself and Tirek to his island.
