Diesel 10 and the doubles wobbled through the forest until they came across rails, relieving the tired and dizzy ex-diesel.

So he placed Stephanie down, but the weight of his body and the dizziness caused him to fall on his side in between the rails.

"10?" Stephanie perked, noticing the other Diesel 10s were either leaning on a tree or sitting on the ground after two of them placed P.T. Boomer and Ember down. "Are you okay?"

Diesel 10 did not respond as he tried to get up from between the rails, but the world started spinning when he attempted to stand up, so he laid back down, placing a hand on his head as he felt a faint headache coming.

The Pinchys were confused, making noises and looking at their owners, even glancing over at Stephanie as if saying, 'What's wrong with him?'

"Stephanie," P.T. Boomer spoke, placing a hand on her shoulder. "I think you should use the Gold Dust now. This doesn't look good."

Sure enough, Stephanie noticed strange veins on Diesel 10's neck, seeing they looked like the three Dusts used on him.

Stephanie reached into her garment and removed her Dust Whistle, changing the symbol to gold as Diesel 10 readjusted himself to be a little comfortable.

She blew her whistle, and Gold Dust came out of the whistle, swirling around Diesel 10 and the others before disappearing.

The doubles disappeared, and Diesel 10 is finally back to being himself, but still had that dizzy expression as Pinchy lifted a little.

"10?" Stephanie spoke as she walked towards Diesel 10. "Are you okay now?"

"I think so," Diesel 10 responded, looking down at his buffers before sighing in relief.

He was finally transformed back into himself, and it was one long day for him to be a human.

Stephanie inspected Diesel 10 to see if there was anything on him or something out of place, seeing there were no veins and everything looked fine.

She checked inside the cab, and everything looked fine as Diesel 10 felt that dizziness was fading along with his headache.

Ember walked over and asked, although slightly startled by what she had experienced, "Okay, what was that I saw? First, something was in the tunnel! Second, a huge monster chased Stephanie after the little goblins grabbed her! And then Diesel 10 grew after multiplying!"

"Ember," P.T. Boomer started before stopping when Stephanie approached her. "Ma'am, I can explain everything to you. But, may I have Notches and Lucy back?"

Ember nodded and handed Notches back along with Lucy as Notches climbed into Stephanie's hood, and Lucy was sitting on her shoulder.

"Now, let's start at the beginning of what is happening," Stephanie spoke, pushing her glasses into place. "While searching for a Gate that I need to find."

"I can help with that," Diesel 10 responded, still feeling his headache but not dizzy anymore. "Just hop on board, and I can take you there."

"Thank you, 10," Stephanie thanked before climbing into Diesel 10's cab.

Ember and P.T. Boomer do the same, and Diesel 10 starts moving forward, although a little shakily because he semi-forgot how to move as a diesel instead of a human.

Throughout the journey, Stephanie explained everything to Ember and P.T. Boomer, ranging from the Black Zodiacs chasing after her, the Zodiacs she needed to unlock to defeat the Nightmares, and learning a little about Sodor.

This instantly puts Ember into a huge rabbit hole as she becomes interested in what Stephanie explained, asking what else did Stephanie learn.

So Stephanie and Ember chattered while P.T. Boomer was just unamused while looking around to search for the 'gate.'

To him, Stephanie and Ember were like parrots talking with each other in the backseat while he was the one 'driving.'

Diesel 10 also hears the conversation and listens to it with curiosity, knowing if he will continue being his usual 'evil' self… maybe listening to a few topics from Stephanie and Ember would help.

Stephanie's pocket watch then trembled, which caused Stephanie to stop talking, saying, "Excuse me." before taking her pocket watch out, looking at it as the top of the leaves of the flower were pointing forward.

"I think we're getting close," Stephanie responded as Ember looked amazed.

"Does this happen all the time?" Ember asked.

"Nah, it happens if I'm close to a gemstone or a gate," Stephanie answered. "Which means that we're getting close."

Diesel 10 hummed with confusion after Stephanie explained before he suddenly bumped into something solid in front of him, causing him to be startled as he pushed back thanks to his buffers.

He looked at what it could be and saw what looked like a massive invisible gate with a lock in the center made of air.

…Solid air?

Stephanie, Ember, and P.T. Boomer had been launched forward accidentally when Diesel 10 bumped into the air-like gate, and Stephanie perked, seeing the gate itself.

"That must be it!" Stephanie smiled as she hopped out of Diesel 10's cab.

She walked over to the gate as Lucy climbed into her palm, transforming her bracelet into a key as the gemstone was turned into a pearl.

Lucy entered the key into the lock and turned it, unlocking the gate as it opened, allowing the group to enter as Ember grew curious.

"Well," Stephanie began as she turned to Diesel 10. "I guess this is going to be your-"

Something grabbed Stephanie's wrist and yanked her forward, causing her to yelp as she went further into the opened gate, as Diesel 10 exclaimed, "Not again!"

So Diesel 10 went after Stephanie into the open area before the 'gate' behind him closed, disappearing as it only showed rails.

Diesel 10 looked confused as he noticed he entered what looked like a massive library filled with many books, and the faint smell of paper and ink lingered in the air.

He thought the place would be filled with clouds and such… not a gigantic library!

Diesel 10 went further into the library, noticing the rails underneath him were magically moving forward with him and disappearing when he moved away.

Strange, but it is magic, so what is the difference?

Diesel 10 soon turned around and heard what sounded like a voice speaking, wondering who it could be as he went further.

He soon entered what looked like a large opening of the library, which could be the middle, and Stephanie was standing in the middle, being inspected by what looked like a doll.

She has fair skin, blue eyes, and lines around the joints as she inspects Stephanie's long blue hair, feeling it between her fingers thoughtfully.

She wore a green uniform with a blue over the right shoulder short cape with sun shapes, a staff with a red crystal on top, long brown boots, a small cap, and potion bottles on the belt around her waist and thigh with a pouch on the other.

"Interesting," she muttered as she felt Stephanie's ears, causing Stephanie to flinch as her ear twitched from the brush of her fingers. "I have never seen any human like this before!"

"Hey!" Diesel 10 exclaimed, causing the stranger to turn around. "Who are you? And what are you doin' with Steph?"

"Ah, i-it's okay, 10!" Stephanie exclaimed as she turned to Diesel 10 with a curious expression. "She is the Gemini Zodiac Protector!"

"A what protector?" Diesel 10 blinked with confusion as P.T. Boomer, and Ember stepped out of his cab.

"A Gemini Protector," the doll responded, pushing a monocle into place. "Someone who protects the Gemini Zodiac from dangers, like the Black Zodiac you and Stephanie fought against."

She paused as she walked up to Diesel 10, feeling his cheeks as he muttered, "Oh, not again." but stayed still as she looked around him before humming as she had a hand on her chin.

"So, is this what a diesel looks like?" she asked, turning to Stephanie.

"Yes," Stephanie nodded. "Not all diesels looked the same, though. Some have pretty cool appearances and diverse personalities."

Diesel 10 was caught off guard after Stephanie explained to the doll, his cheeks blushing slightly as Ember asked, "What's your name?"

"Oh!" the doll perked as she blushed with embarrassment. "Where's my manners? I'm Isadora, the Gemini Zodiac Protector."

"Pleased to meet you," Diesel 10 nodded. "I'm Diesel 10."

"That's your name?" Isadora asked with confusion.

"Yes, and that's the only name I'm going with, too," Diesel 10 nodded with a huff.

"Very well," Isadora nodded before turning to Ember and P.T. Boomer. "And who are you two?"

"I'm Ember!" Ember responded with excitement.

"And I'm Pete Tiberius Boomer," P.T. Boomer responded. "But you can call me P.T. Boomer."

Isadora turned to Stephanie and asked, "Are they your friends?"

Stephanie made the 'so-so' mention with her hand as Isadora looked confused, and Stephanie responded, "It's a little complicated, but they are sometimes a step ahead of me."

Isadora nodded after Stephanie explained, saying, "Let's go find Juzeth, Fu, and Tatonga. We can help stabilize your Zodiac Pocket Watch."

"Wait, there's more?" Ember asked. "I thought there was only one Zodiac Protector?"

"Nope," Stephanie responded with a smile as they followed Isadora. "There are four Zodiac Guardians for each Zodiac that represents in the Celtic, Chinese, Native American, and Western Zodiac Astrology."

"And how many is that all together?" Ember asked.

"Thirteen," Stephanie responded, causing P.T. Boomer to look confused. "And since there are four sets, there are fifty-two Zodiacs altogether."

"Whoa!" Diesel 10 exclaimed. "That's a lot of Zodiacs! And you are controllin' all that on a pocket watch?"

"Yes," Stephanie nodded, taking out her pocket watch and showing it to him. "Zodiacs represent time in the world and how humans have Zodiacs that determine their personalities, so the creators made this to help balance that."

"Exactly!" Isadora nodded as she turned around to Stephanie while walking backward. "And that Zodiac Pocket Watch was made by four creators! I remember some stories from Gemini about how this stranger asked Andromeda for help against the Nightmares."

After hearing the name 'Andromeda,' Stephanie perked, and P.T. Boomer asked, "Who's Andromeda?"

"Andromeda is the Celestial of the Stars," Isadora explained. "She's the one who creates the stars in the sky and constellations! Haven't you heard the stories about Andromeda and her siblings?"

Stephanie made the so-so mention while P.T. Boomer, Ember, and Diesel 10 shook their heads no after Isadora asked, and she said, "Okay, remind me to-"

She bumped into something behind her and landed on her back, causing something to exclaim before standing up and shifting into what looked like a hybrid.

"Ow! Isadora!" It was a human and tiger hybrid wearing a blue Tangzhuang and black pants with the hind legs of a tiger. "What was that for? I was taking a nap!"

"Sorry!" Isadora apologized, sitting up as she pushed her monocle into place. "I wasn't watching where I was going!"

He huffed as he turned to what she was walking away from, seeing Stephanie, P.T. Boomer, Ember, and Diesel 10.

"Who are all of you?" he asked, standing up more as he towered over P.T. Boomer's height.

"Ah, we're with Stephanie," Ember responded, mentioning to Stephanie.

"And I'm the current wielder of the Zodiac Pocket Watch," Stephanie added.

"You are?" he asked as Isadora stood up, brushing herself off as he knelt to Stephanie's height. "How can a young child like you use its powers?"

"How can you carry around that huge sword?" Stephanie responded.

He perked after Stephanie asked and responded with a smirk, "It takes a lot of practice and strength to wield my sword."

"Exactly," Stephanie nodded with a smile.

He chuckled after Stephanie nodded and said, pointing at her with a smirk, "I think I'm starting to like this kid."

"Who's this?" Ember asked, noticing the long tail and ears.

"This is Fu," Isadora responded, mentioning him with a hand. "He's the Chinese Tiger Zodiac Protector."

Isadora turned to Fu and said, "Fu, you know Stephanie, and these are her friends, Diesel 10, P.T. Boomer, and Ember."

"Hmm," Fu remarked, crossing his arms over his chest with a faint suspicious expression. "Friends. Okay."

Stephanie smiled nervously as they continued walking through the library maze, soon reaching another part where they saw what looked like a humanoid snake.

She was blue all over with patterns and had a staff with her that was on her back, long braided blue hair, a long tail, and wearing blue clothes with white pants.

She smiled softly as she turned to the group, revealing yellow eyes as she remarked, speaking with a faint Celtic accent, "You all were a little late coming here."

"Sorry, Juzeth," Isadora apologized. "We were talking to each other."

She gently chuckled after Isadora apologized as she put the book she was reading back on the shelf before saying, "Tatonga went ahead and is waiting at the door back to the Zodiac Dimension. I think she grew somewhat impatient about having to wait."

Fu chuckled after Juzeth explained as Isadora sighed and Stephanie peeked around the two, saying, "Hello!"

Juzeth perked after seeing Stephanie and walked up to her, kneeling as she gently took her hand, saying, "It is nice finally meeting the wielder. You have made impressive yet bold decisions and battled against the Black Zodiacs."

Stephanie blushed as her ears flicked, feeling shy after Juzeth told her as Diesel 10 giggled a little, seeing this looked funny at how blue Stephanie's face turned.

Juzeth chuckled after seeing Stephanie's face blush as she stuttered, "Th-Thank you."

She stood back up as she walked with the two Zodiac Protectors, talking with them as they talked with her.

"I never knew your face could do that," Ember remarked.

"Ah," Stephanie chuckled. "It happens whenever someone blushes with embarrassment or anger."

"What else can you do?" Ember asked with curiosity as Stephanie chuckled.

Diesel 10 stayed silent in the background, listening to the group talking as they continued walking through the library, heading to where Tatonga was.

Soon, they reached the gate to the Zodiac Dimension, and there was Tatonga, a whitetail deer with brown hair and wearing a Native American dress with designs.

She turned to the group as they approached and stood up from the couch, putting her hands on her hips while tapping her foot.

"Sorry, Tatonga," Fu apologized with a chuckle. "We just were coming here at our time."

"A little too long," Tatonga responded with a huff. "But you did come here as you would say. So I wouldn't be all that mad."

Ember was amazed at Tatonga's beauty, seeing whitetail deer from where she was, but never up close before!

Stephanie took out her Zodiac Pocket Watch, and the four tapped it with their fingers, and another vision came to her.


It shows four people talking with each other and handing what looked like parts, two males and two females, and one standing in the background watching, wearing a toga with long blue hair.

After a few minutes, the person in the middle, who was the same one who almost fell off Muffler Mountain, lifted the Zodiac Pocket Watch, opening it, and there were no symbols in it but an empty outer circle.

"It's almost done," the second man, speaking with a Celtic accent, responded.

"Yes," nodded the first woman, wearing what looked like Native American clothes with a wolf's head. "All we need to do is to find Zodiacs."

"I'm sorry," the person watching spoke. "But count me out."

"Wait, why?" a Chinese man stood up, asking with confusion. "What's wrong with them?"

The man stopped and sighed, turning to the group, responding, "They… just don't see me like them anymore. I'm just a shadow to them."

He paused and sighed, "I don't want to return to them. I want to stay here where it is much better than there. But I will help you find different solutions to getting the Zodiacs without contact, okay?"

The four glanced at each other with uneasy expressions before the leader said, "Okay. But maybe we can stabilize the powers after finding another way to get into the dimension?"

"Sure, that can work," the blue-haired man nodded. "Now, let's start with getting gemstones; that way, they can act as an anchor to keep the Zodiacs from going overboard."

"Are you sure this can work, Ustce?" the Chinese man asked.

"I'm sure," he nodded. "There are always loopholes around situations you can get yourself out of."

The shadow looming over the blue-haired figure lifted a little, showing what looked like azure blue eyes with vertical pupils, grinning as he said, "And I know the first four who are easy to get."


The memory disappeared, and Stephanie blinked, looking a little dizzy as she shook her head, holding the Zodiac Pocket Watch in her hand as the others noticed her expression.

"Hey, are you okay?" Fu asked, reaching over to Stephanie and touching her shoulder.

"Yeah," Stephanie nodded, blinking as she had vertical pupils, but they returned to normal after the second blink. "Just a little dizzy."

Isadora noticed the pupils' change and became curious but did not speak about it as Tatonga asked, "Do you need to lay down or something to get rid of it?"

"No, it's fine," Stephanie responded, looking at her Zodiac Pocket Watch before putting it away. "It's slowly disappearing."

The four Zodiac Protectors glanced at each other after Stephanie assured them before she asked, "Do you want to head back to the Zodiac Dimension?"

"A Zodiac Dimension?" Ember echoed with confusion. "There's a dimension?!"

"Yes!" Stephanie nodded with a smile. "It's where the Zodiacs," she mentioned to the four Zodiac Protectors with a hand as they walked down a hallway. "Live in and determine a newborn baby's birth date and zodiacs."

"Really?" Ember perked with curiosity. "Does that mean they know what kind of zodiacs Boomer or I have?"

"Yes," Isadora nodded, turning around and walking backward to speak to them. "But most of the records we have are missing because since we have to scatter because of the Nightmares appearing and the Zodiac Dimension being taken over, the records all had to disappear to keep everyone safe."

"And you're the one keeping track?" Stephanie asked, mentioning Isadora with a hand.

"Yes, but no," Isadora nodded. "Violet, the Capricorn Zodiac Protector, writes all the birthdates down with Zodiacs and tasks me to sort through them. And either me or Jī, the Chinese Rooster Zodiac Protector, would determine the elements, and that's it!"

"That sounds like one busy job you have!" Diesel 10 remarked, noticing the tracks still magically appeared underneath his wheels as he followed the group.

Isadora nodded before bumping into someone behind her, and something squeaked before a voice exclaimed, "Hey, watch where you're going, Issy!"

Isadora glanced at who she bumped into and saw an irritated Shu, and she blushed a little, apologizing with a bow, "Sorry, Shu! I got distracted while talking again."

Shu huffed with his arms crossed over his chest as Fu laughed, ruffling Shu's hair with his hand as he remarked, "Never changed, did you?"

Shu glared at Fu's arm as Niú chuckled a little, putting one arm over Fu's neck and saying, "It's been a while, brother!"

Fu chuckled as Eoghania exclaimed, "Juzeth!" and ran towards her, hopping over everyone and dodging Stephanie before hugging Juzeth.

"Ah, careful, Eoghania!" Juzeth heartily laughed.

"A don't care!" Eoghania exclaimed. "I'm juist happy thon ma sister is back!"

Chayton and Adriel hugged Tatonga when she approached the two, and Chayton said, "Welcome back, sister."

"It's good to be back, sisters," Tatonga smiled.

Amelia excitedly hugged Isadora as Constance did the same, picking up the two with a bear hug as Amelia's tail wagged happily.

"Wow," Diesel 10 remarked as he noticed the Zodiac Dimension. "This is the Zodiac Dimension?"

"Yes," Stephanie nodded as the group glanced at Diesel 10, Ember, and P.T. Boomer. "This is the dimension itself."

She took her Zodiac Pocket Watch from her blue jeans pocket, pressed the top, transforming into her falcon harpy form, and flapped into the air, responding as she hovered, "It's so large there are barely any ceilings!"

Ember looked amazed at what she saw as P.T. Boomer called, "Be careful! You can't handle being that high up in the air."

Stephanie giggled as she reached up to her necklace, taking it off as she transformed back, landing perfectly on her feet before opening it, changing from twelve to two, and saying, "I want to try out the new ones!"

She pressed the top and transformed into her Gemini form, looking like herself as Diesel 10 responded, looking confused, "Nothing happened."

Stephanie made the 'one-minute' mention with her hand before magically splitting herself into two, holding hands as the blue-haired Stephanie said, "Ta-da! We can split ourselves using the Gemini Zodiac!"

"Wait, what?!" Diesel 10 exclaimed as Ember approached the two Stephanies, looking amazed.

"T-This is fantastic!" Ember remarked, looking at every inch of the two Stephanies bodies. "Every inch of you is the same! There's nothing different other than the hair."

"Don't forget personality!" The blue-haired Stephanie happily chirped while the others just stayed silent.

Ember knelt in front of the dark blue-haired Stephanie curiously, seeing how the long hair covered her face, and asked, "Is she alright?"

"Not really," the blue-haired Stephanie shrugged her shoulders. "She's been like that for a long time… but you're fine, right?"

"Yes, I am." the dark blue-haired Stephanie quietly nodded. "You all don't have to be worried about me."

The blue-haired Stephanie smiled softly after the dark blue-haired Stephanie responded as Isadora responded, "You both can split more too."

"Really?" Both Stephanies perked after Isadora pointed out.

"Yes," Isadora nodded. "Each split represents your emotions and what you are."

Both Stephanies looked at each other after Isadora explained before focusing as they split into two, showing what looked like two more blue-haired Stephanies.

The blue-haired Stephanie opened her eyes and saw what looked like a younger child of herself as she was kneeling to the child's height, and had innocent eyes with a necklace around her neck with the symbol of Gemini, but the right side of the symbol.

The blue-haired Stephanie happily squealed as she picked up the child, hugging her.

"This is so awesome!" the blue-haired Stephanie happily squealed while hugging the child. "Oh, you're so cute~!"

For the dark blue-haired Stephanie, she had another version of herself, but with a darker shade and a semi-gruff expression, with her clothes a little scuffed as if she had been in a battle with the same necklace, but the left side of the symbol.

"Huh," the fourth Stephanie responded, crossing her arms over her chest. "Strange seeing another face of mine."

Then she noticed the people around her and became semi-aggressive, asking as she stepped before the three Stephanies, "Who are you? And what-"

"Calm down!" The blue-haired Stephanie exclaimed. "They're friends!"

"'Friends?'" The fourth Stephanie echoed as the third Stephanie walked up to Fu, who noticed the little kid approaching him. "How can we have fri-?"

She stopped talking after seeing little curious Stephanie walking up to Fu, feeling his tail with her hands as he watched, although his ears were a little flat.

"Hey!" The fourth Stephanie ran towards the third Stephanie and scooped her into her arms, exclaiming, "You don't randomly grab a tiger's tail!"

She paused as she looked at Fu with a distrusting expression and a glare before walking away from Fu, carrying the little kid in her arms who was watching from over her shoulder.

"Ah, sorry about that!" the blue-haired Stephanie apologized. "We don't usually agree on a few things."

She made the 'come here' mention to the group of Stephanies before hugging, refusing back to themselves as she reached up to the necklace, taking it off as it transformed into the Zodiac Pocket Watch.

"Did something happen?" Stephanie asked, looking over to the group.

"Somewhat," Diesel 10 responded. "One of you was being a little distrustful towards us."

"Strange," Stephanie replied but secretly had a worried look in her eyes. "Let's see what else is there with the power."

Stephanie tapped the top and transformed into a half-snake and half-human hybrid, her body covered with scales, except for her palms, as the scales only covered the back of her hands and stopped at the bottom of her neck.

Her lower half resembles what looked like a boa constrictor, except with dark blue scales, distinguished blue patterns, and a lapis lazuli underbelly.

Stephanie's height grew a little, towering almost ten feet, and her lower half was longer than Gordon himself!

Stephanie opened her eyes, and they were the same azure blue, except the pupils were vertical.

She looked down at her hands, seeing the scales as she was wearing a dark blue shirt with long tight sleeves and the bottom flowing slightly in a short dress covering the human half, except for the lower half.

"Whoa," Stephanie remarked as she looked at herself, even at her lower half. "Thisss isss cool!"

Stephanie flinched when she uttered the 's' in her words, causing her to hiss a little as she perked, noticing she was flicking what looked like a forked tongue.

"Hmm," Stephanie hummed before hissing, seeing a dark blue forked tongue flicking from her lips, practically smelling the air.

For Diesel 10, he had never seen a snake before (or even this big), but Stephanie's appearance made him semi-afraid.

"This is," Ember starts, looking at Stephanie's body and lower half. "Fantastic! Are you comfortable being like this?"

"Yes," Stephanie nodded, turning to Ember, moving down a little to her height but was not hissing anymore. "The scales are a little itchy, but it's fine."

She reached up to her necklace with the snake pendant and took it off, transforming back to herself before tapping the top again, transforming into her half-deer and half-human form.

She has the whitetail deer appearance but her clothes transformed into what looked like Native American clothes, except the lower half has the body of the deer and antlers.

"You can transform into any form using the pocket watch?" Ember asked with curiosity.

"Yes," Stephanie nodded, reaching up to her necklace and taking it off, returning to normal. "But it only works one at a time because fusing two or more zodiacs can overwhelm or, worse, damage the Zodiac Pocket Watch."

She taps the Zodiac Pocket Watch and transforms into the Chinese Tiger Zodiac, her form resembling a Sumatran tiger, with pure white hair, claws, and the ears and tail of a tiger.

She wears a blue cheongsam with long sleeves and reaches down to her ankles with hidden designs of chrysanthemums that semi-blend with her cheongsam.

"Huh," Stephanie remarked as she looked at her clothes and body. "This is interesting!"

She focused and shifted into her animal form, transforming into her complete tiger form, and looked at her paws, speaking, "I like this form! So fluffy!"

Ember knelt at Stephanie's height and reached over to her face, feeling her fur as she stayed still, giving little chuffs as she gently nuzzled them.

"You can transform into your animal forms too?" Ember asked, and Stephanie nodded. "I didn't know it could do that!"

"I didn't either until my first time using the Zodiac Pocket Watch," Stephanie explained before shifting back to her half-tiger form as Ember removed her hands from her face. "But my cat Notches helped me learn how to use the watch a few times. And yes, I can hear him speaking to me."

She reached up to her necklace and took it off, transforming it into herself as she put the Zodiac Pocket Watch back into her blue jeans, explaining, "All I need to do is defeat the rest of the Black Zodiacs and free them."

"What happens next?" Diesel 10 asked.

Stephanie paused after Diesel 10 asked her, responding, "I don't know. Maybe get rid of the Nightmares? Or-"

"Battle the Nightmare King," Fu responded, causing Stephanie to perk.

"'Nightmare King?'" Stephanie asked. "What's the Nightmare King?"

"The Nightmare King is the one who rules over all Nightmares, the one who has been sending all these mischievous and dangerous creatures all over Sodor," Isadora explained. "He's dangerous if he is released from prison and would send everyone into a nightmare sleep forever."

"All you need to do is defeat him, and everything will return to normal," Fu explained.

A bad feeling sat in Stephanie's stomach at the thought of defeating someone more powerful than she was as P.T. Boomer asked, "But do you know where the Nightmare King's prison is?"

"No, we don't," Chayton responded. "The entrance to the prison varies from how the person locks the Nightmare King away, and it would be difficult to find where it could be."

"Well, that's the sign we need to research where he could be," Ember responded. "And that means spending a long time in the library!"

"Slow down, Ember," P.T. Boomer calmed Ember from being too excited.

"We can help by finding where it is if Stephanie finishes collecting all the Zodiacs," Shu responded. "Then we can properly use the Great Pool to search for it."

"That's great!" Stephanie smiled before turning to P.T. Boomer and Diesel 10. "But that means you guys will not do anything stupid into doing anything toward the Zodiacs, right?"

"Maybe," Diesel 10 responded with a huff. "But since you told and showed us, I don't think we'll be messing around with the Zodiacs for a long time."

"Good," Stephanie nodded. "Let's leave the Zodiac Dimension. I will take a long break from doing many things today."

Diesel 10, Ember, and P.T. Boomer looked at each other after Stephanie sighed and shrugged a little, following her from behind as they exited the Zodiac Dimension and back to Sodor, right at the same spot where the gate was.

"Right," Stephanie nodded with a tired sigh as she looked at the night sky. "Time to head back."

She drew a door in front of her before opening it, stepping inside as it was in her room in Sir Topham Hatt's mansion.

Diesel 10 and the others looked surprised after seeing it as the door closed, and Diesel 10 asked, "She has a lot of tricks up her sleeves, doesn't she?"
