	“Twilight, I have discovered the test that best suits you.” Yen Sid said suddenly.
“What is it?” Twilight asked, still anxious about a test.
“Are you aware that two hearts reside in your body?  One heart is of hope and love while the other is of fear and regret.” Yen Sid explained.  “I feel that a test in which you explore this second heart is appropriate.”
“Exploring Vim’s heart?” Twilight didn’t understand, how could somepony explore a heart?
“Sit down here.” Yen Sid pointed to a chair in the corner of the room.
Twilight walked over to the chair and sat down.  She let her body slowly relax until Yen Sid cast a spell on her that out her into a deep sleep.  His voice was still audible in her sleep, but she wasn’t sure if it was part of a dream or not.
“Twilight, you must search your heart for the point where your heart meets hers.  Once you find that point, you must enter her heart and resolve her internal conflicts.  Her heart is broken in a way that I’ve never seen.” Yen Sid’s voice rang through the empty void.
“But how will I find it?  How will I find her heart?” Twilight called back.
“Her heart is connected to yours in the place where your path separates.” Yen Sid’s voice trailed off, until it became inaudible after the statement.  If there was any additional advice that was intended for Twilight, she was unaware of it.
Seconds later, Twilight watched in awe as an entire world formed around her.  She found herself surrounded by mazelike walls of bookshelves.  It was like a giant library, which Twilight found to be useful.
“Libraries are organized, that can help with finding Vim.” Twilight said to herself as she started making her way through the enormous library.
Twilight calmly walked through the narrow paths between the towering bookshelves.  Her mind drifted as she traveled, wondering where Vim’s heart would be.  In a library, stories can fit into so many categories; it could be under “V” for her name or maybe “M”, there was the possibility of it being under “S” for Sombra since that was when they last really saw each other, unless she took into consideration the waterfall in Twilight Town.  There might even be a chronological section, which would be her first choice.
She teleported herself to where she would have placed an area for her life in chronological order.  Every year of her life had its own door.  She started at the very end, right about the time that Vim had died.  To her surprise, there were two doors that had her current age listed.  Twilight stepped through the second door, just out of curiosity, a trait that seemed to get the best of her more often than not.
On the other side, she saw that it had doors for everyday leading up to when Vim died.  Not a single day past that fight was in the corridor.  It didn’t make sense.  A lot of things had happened since she beat Sombra, so Twilight stepped through it, thinking that there was a chance that it was Vim’s memory.
Once she passed through the door, she was unable to interact with anything.  She watched through Vim’s eyes as the pony cast a teleportation spell.  The pain was unspeakable as she felt the body tumble to the ground.
“Go now… avenge… our dragons…” Vim whispered through a cracked voice.
Twilight couldn’t bear the thought of having to see Vim die again so she backed out of the memory.  She didn’t want that to be where she had to go, she couldn’t help with anything when Vim was already dead.  Twilight retreated back to the corridor and galloped into the main part of the library once again.  She walked down the wall of doors that led to each and every year that she had lived.  Each door had a second door for the same year sitting right next to it, Vim’s doors.
She walked until she reached the year before she had taken her entry exam to get into Princess Celestia’s School for Gifted Unicorns.  At that door, there was only one.  The implication of what that meant made no sense though.  It meant that before Twilight became Celestia’s student, Vim didn’t exist; it meant that she was barely older than the Cutie Mark Crusaders.
Twilight back tracked to the year that she’d taken her exam and walked into Vim’s door for that year.  She walked into the earliest memory that Vim had, expecting to see from the eyes of a newborn foal.  Instead, the princess was met with a very similar scene.  She was in the small classroom with four ponies judging her as she attempted to hatch Spike’s egg.
“This is my memory though…” Twilight shook her head.  “Did I go through the wrong door or something?”
She watched through her own eyes as she struggled with hatching Spike’s egg, and just when the little filly had given up hope, Twilight expected there to be a loud blast, startling her and helping her hatch the egg.  Instead, there was nothing.  Absolute silence aside from the sound of quills scratching across paper.  One of the judges climbed to his hooves.
“I’m sorry Miss Sparkle, but you didn’t pass.  I would advise more practice and I wish you better luck next year.” the stallion said before leaving the room with his three companions.
Twilight watched in horror as her father approached her and gave her a warm hug.  “I’m sorry honey, how about we go out for ice cream and try to make the best of the day?  How’s that sound?” Night Light asked.
Twilight wanted to cry, she didn’t know what was going on.  Nothing was right, she was supposed to pass the test, not fail.  She wanted to accept her father’s offer, but instead, when the filly spoke, she said something that Twilight would have never imagined.  “No!” the filly shouted angrily.  “I don’t want to go to this stupid school anyway!  Princess Celestia doesn’t deserve me!” It was an anger fueled by sorrow that caused her to shout.  The older Twilight didn’t understand why she would have ever said anything like that.
“Twilight dear, your father is just trying to be nice.  You should apologize for yelling at him like that.” Twilight’s mother, Velvet, argued.
The filly Twilight sobbed as her parents both tried to comfort her.  The older Twilight left the memory, unsure of what she had just seen.  It wasn’t correct, something had changed her memory, unless…  She had to be sure.  She went into the next memory, the day after the test.
She was sitting alone in her room with the lights off, trying to read a spell book.  The filly was mumbling incoherently as her door was being beaten on.  Twilight had no control over the body, seeing as she was just a guest in her own memory.
It was hard to see the book, but eventually she saw the kind of spell that the younger her was reading about.  It was dark magic, darker than even what King Sombra had been using when she’d fought him in the Castle of the Two Sisters.  Twilight knew about the spell, but only because of a warning from Princess Celestia to avoid even reading the book.  She was given an example of what one of the weaker spells was capable of, and that was to destroy matter that was surrounding the spell caster.  If cast improperly, the spell would only result in an explosion with a blast radius of about a hundred feet, destroying, but still leaving the rubble, of everything surrounding the caster.
Twilight wondered why she would ever be looking at a book like that, or how it even came into her possession.  It was supposed to be under strict protection by a small army of guards and only Princess Celestia herself was allowed to see it.
The beating on Twilight’s bedroom door intensified and the filly turned around slowly to check her barricade.  All of the furniture in the bedroom had been forced up against the door, holding it closed against the force outside.  Twilight could faintly hear her mother and father shouting from the other side of the door, pleading with her to just come out and talk.
The filly turned back to her book and started trying to cast the spell.  Her horn flared up a lilac aura that expanded as she channeled more and more power into the spell.  Twilight wanted more than anything to close her eyes, to stop herself somehow.  She was powerless though, unable to save her family.
“Twily!” Shining Armor’s voice shouted from the other side of the door, causing the filly to turn her head back to the door, interrupting her spell.
The incomplete spell caused a massive explosion, destroying her entire house and rendering the filly unconscious.  While asleep, she could hear a voice, one familiar to the older mare, but foreign to the youthful filly.
“Come to me and I will save you.  I will take you in and give you a place to call home.  A chance to seek revenge on the princess that caused all of this.” the voice promised.
“Who are you?” demanded the filly.
“I am King Sombra.” the voice answered.  “And what is your name, little filly?”
“Twilight Sparkle.” the filly snipped back.
“Hm, this is an interesting turn of events.  For me, this is our second meeting, but I think that for you, it is our first.  If you become my pupil, I can teach you how to control the darkness in your heart.” Sombra promised.
“What’s the catch?” Twilight asked back.
“Eternal servitude and unquestioned loyalty to me.” Sombra demanded.  “Should you choose to accept, the Twilight Sparkle that the world knows will die and Midnight Vim will be born.”
“I… accept.” Vim gulped, unsure of what she had just promised.
Twilight fled from the memory, retreating back to what she knew.  Those memories terrified her, but they told her so much about Vim.  Twilight and Vim were closer than she could have ever imagined before that moment, they were the same pony.  When Master Yen Sid told her to go to where they separated, he meant the day that she became Vim.  Twilight understood what had caused it, but she didn’t know how to fix it.
“Now you know.” Vim said from a dark corner of the corridor.  Her robe was off for the first time in years; she was through hiding.
Vim’s hair was styled just like Twilight’s except for differences in color.  Her hair was primarily black aside from two streaks of red that were right next to each other.  The streak that was closer to the center of her head was much darker, the color of old blood, while the one that was closer to the outside was slightly lighter.
“I- I’m…” Twilight tried to speak but couldn’t get the words to form properly.
“Where you succeeded, I failed.  When you gained friends, I helped to bring the world to its knees.  When you learned to love, I learned only to hate.” Vim said calmly.
“How am I supposed to help you?” Twilight asked.  “If all of this happened in your past, then how am I supposed to change anything?”
“I don’t know.” Vim shook her head slowly.  “Isn’t that the point of the test?  To find a way to help?”
“How did you… oh, yeah.  I’d forgotten that everything that I see, you see.” Twilight paused for a few moments.  “Maybe if I keep going through your memories, I can find a way to help you.”
“This is the day that I got Blade.” Vim pointed to a door that was a little farther down the corridor.  “It’s the next significant moment in my life.  I am not proud of my actions that day, nor am I proud of how I treated him, but it cannot be changed.”
Twilight nodded and walked into the doorway.  She once again found herself in Vim’s body, seeing only what Vim could see and feeling only what Vim could feel.  It was dark and cold; the only light was coming from the moon.
Vim began to walk, taking Twilight with her as she entered the castle.  She followed after King Sombra, intending to test Vim’s loyalty.
“This is what that training was for.  She won’t expect you to attack her.” Sombra smiled that sickening, comforting smile that he always gave Twilight.
“I’ll kill her.” Vim said coldly.  “It’s all I’m good for, right?”
“Yes.” Sombra nodded.  “It is your one purpose.”
Twilight couldn’t believe what she was hearing.  After all of the effort he went through to get Twilight on his side, he seems to not care for Vim at all, even from the start.  Why would she stay with him after seeing that he didn’t care for her, Twilight had to know.  Before that though, Twilight had to make it through the memory that she was currently in.  It was imperative that she find out everything, including how the other Princess Celestia was defeated.
“Who’s there?” Celestia asked as the filly and the king entered the room.
Sombra had cloaked himself in shadows so that Celestia would be unable to see him and he could watch the events unfold without being bothered.  If Vim succeeded, then it was all said and done, but if she failed, then Sombra would step in and kill both his student for failing and the princess who defeated her.
“A filly?” Celestia asked, lowering her guard and approaching Midnight Vim.  “What are you doing here, child?”
Vim didn’t answer.  She started blinking rapidly, hoping that the princess would notice that something was wrong.  Twilight could hear her every thought.  She didn’t want to die, but if she fought the princess she was dead, and if she refused then Sombra would kill her.  Maybe she could survive if she could just warn Celestia without giving herself away.
“What’s wrong?” Celestia asked kindly.
Vim stayed perfectly silent.  She looked up at Celestia and when their eyes met the sun princess doubled back.  In the split second that their eyes were locked, Twilight was able to see Vim’s reflection in Celestia’s eyes.  Vim’s eyes were a bright green and had the dark smoke emanating from them like what happens when a pony is using dark magic.
Without any warning, a blast of dark magic shot from Vim’s horn.  Celestia was slammed into her throne, toppling the royal seat.  Twilight was unable to see Celestia until a yellow bolt shot from the throne, striking the filly and slamming her into the floor head first.  Vim slowly tried to get back onto her hooves, but instead of stopping her, Celestia’s attention turned to the door that Vim and Sombra had entered through.
“Sombra!  Show yourself you coward!” the princess demanded.  “I knew that you were scared of a fair fight, but sending a filly to do your dirty work is just sad.”
Vim attempted to cast another spell, but she found that all of her magic had been drained.  That attack from Celestia did no physical harm to her, but it drained her of all of her energy.  The filly could barely find the strength to stand, much less fight a god.
“Was it that obvious?” Sombra asked, revealing himself.  “Tell me Tia, are you willing to kill a child?”
“What are you talking about?” Celestia snipped back, glaring down at the king.
“No matter how this ends, the filly will die.” Sombra answered.  “Either you kill her directly or indirectly.  If you don’t kill her yourself, then I will be forced to kill her for failing to kill you.”
Celestia looked between the two of them.  The life of a filly was in her hooves and it was clear that she was faced with uncertainty.  There was a single loophole that she could find, kill Sombra so that the filly would be free, but that would cause a major scene in which the filly could die in the crossfire.
Twilight knew how the story would end, she knew that Vim had claimed to have killed the other Princess Celestia and Sombra had not argued.  If it were a lie and Sombra was the one to have killed her, he would have spoken up, probably beaten her knowing him.  Twilight didn’t want to see it, but she had no choice, it wasn’t like she could close Vim’s eyes or change her actions.
While Sombra and Celestia stared at each other, Twilight could feel a power flowing through Vim’s body.  It was a familiar energy, just like what Twilight had felt when she was startled by the first Sonic Rainboom.  A bubbly dark purple beam shot out at Princess Celestia while she was distracted.  There was no recoil on the princess’s part, instead she just fell.  It lacked any of the emotion that Twilight was expecting; it was so calm that it was almost peaceful.
“Well done.” Sombra smirked.  “This castle is yours now.  Do with it as you please.” Sombra walked out of the throne room, leaving the young Vim and the deceased princess alone.
Vim walked away from the throne room and made her way to one of the towers.  Specifically the tower that she took her test in.  Once inside the testing room, she saw the egg was still sitting on a table.  She gripped it with dark magic and helped it hatch.
Instead of looking like Spike did as a newly hatched dragon, this dragon was slimmer and slightly longer.  It seemed more grown up than Spike did even now, years later.  It was Blade, the dragon that had been staying with them in the castle while Twilight was forced to stay with Sombra.
“I passed your bucking test.” Vim growled.  “I’ll call you Blade.”
Twilight felt herself being pulled out of the memory.  She was face to face with Vim once again.
“There are two more that you need to see.  The day before Mist Valley escaped to your world, and the day that I met the Overlord.  Come with me.” Vim led Twilight out the door and took her a few years down the road.
They ended at about the time that Twilight would have arrived in Ponyville, but that made no sense to her.  Mist Valley arrived ten years ago, but this was only about three years or so.  Vim must have noticed Twilight’s confusion because she stopped before opening the door.
“Something wrong?” Vim asked calmly.
“The timeline, it doesn’t make sense.” Twilight’s face contorted into an expression that accurately portrayed her confusion.
“Have you ever been into the Star Swirl the Bearded section of the Canterlot Library?” Vim asked, stopping in front of a door in the inner corridor.
“Yes, I have.” Twilight nodded.
“You may be aware that he has a time spell then.  I used that time spell at about this time to go back and try to stop Mist Valley’s entire group from escaping.  As a filly, I was unable to, but we know that we stopped one of them and nopony was taking credit for it.  I figured out how it happened though, that I had gone back in time and met them as they escaped.” Vim explained.
“And this is before you cast the spell?” Twilight asked back.
“Yes, this is the day that the light almost saved me from the darkness.  The day that I met… you’ll just have to see for yourself.” Vim opened the door and waved Twilight to it.
Twilight stepped through the door and found herself in the form of a mare.  She was walking around in an abandoned building, something about which felt familiar.  It took her only a few seconds to realize the events that were transpiring as a dark, night sky like, fog formed on an overhead balcony.
“Where are my subjects?” Nightmare Moon asked as her body formed from the smoke.  “Was my sister not supposed to be holding her precious celebration here this year?”
“Your sister has fallen.” Vim explained.  “Princess Luna, come with me, my master wishes to meet with you.”
“Your master?” Nightmare Moon glared down at Vim, “Was he the one who defeated my sister?”
“No, it was me.” Vim said almost solemnly.
Twilight saw something that she was not expecting.  She saw Luna’s eyes, not Nightmare Moon’s, but Luna’s eyes staring back at Vim.  “You harmed my sister?” there wasn’t anger in her voice, in fact there was no emotion at all.
“Yes, I beat her.” Vim answered.  “My master commanded i-” Nightmare Moon’s celestial mane wrapped itself around Vim’s throat, stopping her mid-sentence.
“Who is this master of yours?”  Nightmare Moon asked as she started to change back into Luna.
Twilight could only assume that the love she felt for her sister was what was bringing her back.  She’d thought that the Elements of Harmony were the only things that were capable of saving Luna from the Mare in the Moon, but it didn’t seem to be that way.  It seemed that Luna was capable of saving herself, that the Elements may have just helped her.
“King Sombra.” Vim answered.
“And he had you kill Celestia?” Luna asked, having fully changed back to herself.
“He would have…” Vim whispered.  “In Canterlot, your sister built a castle.  She is still there, and she is still alive.”
“Take me to her!” Luna demanded.
Vim created a large bubble of magic and teleported the two of them into her castle.  Vim led Luna into a hidden staircase that went down for what felt like an eternity.  Eventually they reached the bottom of the stairs and they came across a cell that had magic hiding it.  A perception spell, only Vim and those who she allowed were able to see it.  It was the only way she knew of to protect the sun princess from Sombra and his mysterious master.
“Luna…” a hoarse voice whispered from within the shadows of the cell.
“Celestia!” Luna shouted darting over to the cell.  “Are you all right, sister?”
“I could be worse.  Thank you Vim for bringing her to me.” Celestia smiled at the unicorn.
“We don’t have long.  Sombra will have me bring you directly to him, Princess Luna.  If you don’t cooperate with him, he’ll kill you himself.  I won’t be able to save you.” Vim explained.
“Then we will fight him together.” Luna suggested.
“I- I can’t…” Vim choked out.  “If I betray him, he’ll kill me.  I’ve done more than I should have already.”
Celestia and Luna looked back and forth at each other, silently discussing what needed to be done.  Vim had sacrificed so much for them, if she was found out, then she would be killed in a way more brutal than either of them cared to imagine.  They needed to find a way to hide that Celestia was alive from Sombra.  Revealing her survival to the Overlord could actually play out fairly well for them, assuming that he blames Sombra.
“Midnight, please stay here while my sister and I deal with Sombra.” Celestia stated.  “I’ll be hiding my identity so that he will not be able to recognize me, that way you should be safe, should we fail.”
Vim stood there completely silently.  There was no way to respond to that.  The princesses were willing to risk their lives to save their world, and all Vim had done so far is try to survive.  She didn’t feel like she deserved to be near them, they were better than she was.
Celestia and Luna walked out of the dungeon like area, leaving Vim alone.  Once she was sure that the princesses had gotten far enough away, she ascended the stairs.  The castle was as empty as ever, all of the ponies that had once lived within its walls were now dead.  The army of monsters that the Overlord was in control of had seen to that.
Vim paced impatiently until there was a plain line that designated her path.  There were hours of absolutely nothing, until there was a blinding light.
Twilight was unable to see anything due to Vim’s eyes being clenched shut as a reaction to the light.  When Vim finally opened her eyes, she could see Luna standing with an average sized unicorn pony.  Celestia had done an effective job of concealing who she really was.
“Vim my apprentice, teach these two insolent ponies a lesson.” Sombra smirked, waving a hoof carelessly toward the two princesses.
Vim looked at the princesses, and then back to the king of shadows.  Twilight could feel her body shaking; she could hear the barrage of thoughts that were running through Vim’s mind.  “No.”
“What?” Sombra snapped, smacking Vim across the face with his hoof sending her tumbling down to the ground.  “Without me you’d be nothing.”
“Don’t you dare lay another hoof on her!” Luna demanded, stomping her own hoof into the snow.
They were just outside of King Sombra’s castle.  He’d taken the Crystal Empire for his own.  He said something about it being rightfully his before he attacked it.  Vim couldn’t stand it there, it was cold and miserable.
“I’ll do with her as I please.” Sombra looked back to the princess of the night.
“I’m through with helping you.” Vim said as she climbed back onto her hooves.
“Really now?” Sombra looked over at his apprentice and there was a flash of light.
A Keyblade appeared in front of Sombra, the same one that he had used against Twilight when they fought.  He smiled at Vim as he pierced her heart with the Keyblade.  Twilight had never felt such pain, like her heart was being ripped in two.  Her vision blurred into a dark mess as her legs gave out.  She felt like her head hit the floor, but she couldn’t be sure since all of the feeling in her body was gone.
“This Keyblade has the power to unlock hearts.  It will remove the light from your heart, leaving nothing but your darkness.  Your hatred and your fear will empower you, they will make you stronger.” Sombra explained as Vim stood back up.
Vim’s head was still spinning and Twilight could still hear her thoughts.  As Vim took the first step toward the princesses, all the pony could do was wish that she could stop herself.  
Up until this point, Vim had looked just like Twilight, but was her heart was unlocked, she changed.  Her coat turned to a dark grey from its usual lavender.  Her eyes turned into a very light blue and narrowed ever so slightly.  Vim’s mane and tail became an exact match to the hair of the human Vim that Twilight had been seeing lately.  Her cutie mark changed from what it had always been to a lone, black six point star with a red outline.
Vim was gone in that moment.  Something else had replaced her, locked the real her away deep within her own heart.  The new Vim smiled a crooked smile before blasting Celestia and the Luna.  The two princesses fell to the ground.  Vim shot Celestia again, this time with a banishment spell, similar to what Grey had been teaching Twilight back in the library of the Hollow Bastion.
“Leave her.” Sombra stopped Vim from banishing Luna.  “My master wishes to see if she would be willing to join us.  She had betrayed her sister and fallen victim to the dark once already, so the likelihood of it happening again is very high.”
Twilight left the memory of her own free will that time.  She couldn’t bear to see any more of it.  Vim stood on the outside waiting for her, the same as the last time.  Instead of speaking, she simply pointed two doors down, letting Twilight know where her final destination would be.  She would finally meet Haze in a real setting.  So far, her only encounter with him was a brief fight.
On the other side of the door, Twilight once again became the new Vim, the one who had fallen victim to the darkness.  She was standing before a pony that was wrapped in a black cloak and was wearing a pair of goggles.
“Midnight Vim?” Haze asked calmly.  “Is that you?”
“Yes.” Vim answered quietly, lowering her head.
“I heard what you did, how you confronted your master to do what you thought was right.  It was a very noble thing to do… I hate noble.” Haze smirked as he hopped down from a ledge.  “If I ever hear about you doing anything like that again, about you interfering with my plans…”
Vim stared into Haze’s goggles as he lifted them from over his eyes.  Twilight was finally able to recognize why he would hide those eyes of his.  They were solid yellow, just like the heartless.  As the pony removed his cloak, his similarities with the monsters became ever more apparent.  His coat was solid black.  There was only one streak of color on his mane, a dark purple.  The base of his tail was the same shade of purple, but the tip was black.
“I will save you from death.” he continued.  “A life of eternal suffering, and no possibility of death, sounds a lot more interesting.  Or maybe I could kill you and bring you back to life, forcing you to face your ultimate fear over and over for all of time.”
Vim remained unfazed by the threats of the Overlord.  Having her heart sealed in the way it was had taken away all of her emotions.  She felt no fear, no joy, no hate, no love.
“That is, however, only if you stand against me again.” Haze smiled almost happily.
Before the memory could continue, Vim pulled her back out.  The two of them stood in silence, each one expecting the other to speak first.  Vim looked away from Twilight for a few seconds, trying to regain her composure.
“I think that I know how to help you.” Twilight said quietly.  “I’ll share your pain, and you can share my love.  Without your family, I think that you’ve forgotten what love feels like, but I can help you.”
Vim turned back to face Twilight.  “What… what do you mean?”
“You’ve been alone for so long and nopony should ever feel like that.  I want to share my life with you, so that you can live your life like you should have been able to.  So that you can still have your family and so that you can have the friends that you needed.” Twilight smiled before hugging Vim tightly.
“I- I don’t kn- know w-what to s- say…” Vim said through tears.
“You could say yes.” Twilight smiled at her warmly.  “You’re my friend, but you’re also something more, you’re part of me and I’m part of you.  Together we are one pony, and nothing will ever change that.”
“Yes.” Vim smiled back at Twilight.  “I accept.”
“All right.  I’m going to wake up now, but I promise that we’ll get through this.” Twilight said as she opened her eyes and saw the old man pacing behind his desk.
“You’re awake.” he gasped.  “I was beginning to worry.”
“It’s all right Master Yen Sid, I helped her.  I had to understand what she’d been through to know how, but now Vim is at peace.” Twilight smiled as she stood up.
“You have passed your test then.” Yen Sid said as he turned to a window.  “Master Twilight, there is one more thing that you must do before you can return home.  There is a Keyhole that needs to be sealed.  Both Sora and Riku are nowhere to be seen and this world is in immediate danger.  Unless you do something to save it, then it will be lost to the Heartless.”
“A Keyhole?” Twilight asked.
“It is how a Keyblade wielder seals a world off from the Heartless.  If you can make it there before the Heartless, then the world will be saved and so will all of the people who live there.” Yen Sid explained.
“Where is it?” Twilight asked as she walked over to the old man.
“It is the Hollow Bastion.” Yen Sid answered.
“But I was just there…” Twilight gasped.
“There is no time to lose.  Go there immediately.” Yen Sid urged Twilight. “Take this Gummi Ship, it will fly there on its own, all you need to do is be in it when it arrives.”
A strange looking ship came into view of the window.  It looked like building blocks that had been attached together into some foreign shape.
Twilight nodded and teleported on board the Gummi Ship.  Almost immediately the ship took off, leaving the tower and Master Yen Sid behind.
