Serentime.
A large mass of a world divided into three main parts: the Carnifair, the Living Quarters, and the Empty Lands.
Carnifair.
Like a theme park with various game booths, rides, casino games, and eateries or food stands. The color palette is glossy dark pink floors, a vast dark blue sky, and various colors and designs on all the rides and places with a base color of black or blue, and designs in neon pink, green, purple, and yellow.
Living Quarters.
Buildings to house those who live there. Most buildings are dark magenta with black roofs, and they range in height from two stories to seventeen.
Empty Lands.
Vacant of buildings or structures and mostly desert, besides some grass and a few trees. These lands remain vacant because there is a close connection to the dark void in this area, and sometimes dark creatures break through to that area. Some die off or return to the void, but other creatures head to Carnifair.
Defenders.
Appointed beings to protect Serentime from the creatures, and keep peace in the world. Under the authority of Mettatime, the Mettaton of the world.
Pen explained the three parts of Serentime to Ink, and that there are appointed Defenders who protect the world under Mettatime. He was fascinated by the world's structure and how organized and protected it seemed. It made him realize why he never heard of this world since it never needed his help to be at peace to begin with. Though he also felt that the air was different here. He didn't sense the world until he enetered there, but then he also felt a certain oddness being there that he couldn't explain.
They first arrived in a short grassy field of pink and a white expanse of forest outside the field as they followed a cobble paveled road to a fortress-looking wall of three stories made of obsidian that reached out in a semi-circle, and tall golden gates where a booth stood at the side of it that was attached to the wall.
Upon arriving in front of the booth, they were met with a kind bear monster who resided inside as he was typing on a computer with his big paws until he saw them and smiled.
"Hello friends! Welcome to Serentim- Pen! Is that you?" The Bear asked.
"Yes. Hello, Mr. Bear. I came here with a friend to see Serentime. I'm giving him a tour," Pen replied, gesturing to Ink who waved.
"Oh! That's nice. What's your name sir so that I can write you in?" Mr. Bear asked.
"Ink. Nice to meet you," Ink replied.
"Okie dookie, Ink, and you as well. Huh... Pen and Ink... Well, looks like you're all set. Here are the light wristbands and a bag of coins to get you two started since you are new Mr. Ink," Mr. Bear said, as he gave them two wristbands and two sacks of gold coins.
"Thanks. Tell your wife and kids I said hi!" Pen said, as they started walking towards the gate.
"Will do, Pen," Mr. Bear said, as he waved with a big smile.
Pen slipped on her neon purple wristband, as Ink slipped on his neon blue one. They stood before the gate, as Pen lifted her hand and Ink's hand towards the gate so that it could sense the wristbands. The gates opened, and the two entered Serentime.
Two Hours Later:
"It's so lively here! And there's so many things to do!" Ink said, his eyes changing colors and shapes constantly with his stimulated emotions as he kept hoping around where Pen was walking.
"It's such a wonderful world, isn't it? Especially the food. How is the multi-light shake?" Pen asked, gesturing to the multi-colored drink in his hand.
"It's so good! I could drink this all day," Ink said, taking a sip of his drink through the straw.
"It's for energy, and it can heal a cold or poison I believe," Pen said.
"Wow! That's awesome!" Ink said, taking another drink.
"Oh! Come Ink. There's someone I want you to meet. She's my other best friend besides Mirror and a Defender of this world," Pen said, wrapping her arm around Ink's to lead him towards the casino area.
"Is she a gambler?" Ink asked.
"Kind of, though she mostly foresees it to make sure no one cheats, but there's no money in the games mostly. Only tokens. It lessens the feelings of depression that way as Mettatime preferred," Pen said, leading Ink to an outside casino game with a ring-table.
There were players and others gathered around the ring-table, and one person stood in the center shuffling cards.
"Come on! Come on! Come on! Step up and play a hand! See if you can win right before this stand! Throw in your tokens and let the game start. Hurry now peeps before the cards make their mark!" The woman shuffling the cards said, with black hair and golden ends.
"Is that you're friend?" Ink asked, noticing her hair.
"Oh, yes that's her. She's known as Gold," Pen said, as Gold dealt out a few cards to the players at the table.
Gold spotted Pen, as she asked someone who worked there to take her place in the center ring. She made her way outside the crowd to greet her friend.
"Hey Pen. What it up? How you're doing? I thought you weren't coming," Gold said, with a smile on her face, but her eyes couldn't be seen since she wore gold-colored shades.
"Well, I wasn't going to come at first, but then I met my new friend, Ink. We figured out that we know people who we both know, or who know each other. It's fascinating actually," Pen said, bringing Ink towards Gold with her arm wrapped around his.
"Ohhh. I see. Hello Ink. Name's Gold, how you're doing? You're a Sans right?" Gold asked, extending her hand towards him.
Ink took her hand and replied, "I'm doing great, and yeah somewhat. How did you know?"
"I've met a few Sans here and there and in this world, or have heard of a few. Nice to see that Pen made friends with the Guardian of the AU's," Gold said, ending their handshake, as Ink smiled and nodded.
"I invited him here since he's never been here before, and for the Royaltic treat at the end of the week! We have to come here three days right?" Pen asked Gold with enthusiasm.
"Royaltic... ohhh. Oh, yeah! That's right. You have to come here for at least three days with someone else this week to get the special treat at the end of the week," Gold replied.
"Yes! We still have time!" Pen said, with joy and determination.
"Yes, quite. There's still four days left... and what a perfect guy to find," Gold said, speaking her last sentence low enough for Pen not to hear, although Ink heard her.
"What do you mean?" Ink asked.
"Heh. You'll find out~" Gold said, making Ink ponder what she meant.
"Well, enjoy yourselves, dears. Go where you'd like. Serentime is open to all so behave or we'll make you fall," Gold said, especially to Ink.
"Is the food market open?" Pen asked her.
"Yup. They got new specials today. Hurry before the lines get longer," Gold said, and Pen thanked her as she pulled Ink along.
Pen and Ink tried the various foods at the food market until it was time for the shops to resupply, which was the only reason it was closed. They hung out at different places that Pen showed Ink, like a park that was nearby, the lake on the other side, and a garden until they decided it was time to part ways until tomorrow since they each had something to take care of.
Next day:
The two met again in Serentime at the casino where they met Gold yesterday. This time they headed towards the city district where residents of Serentime lived. Pen showed Ink the city, and she showed him where Mettatime is said to live, although no one was really sure. Ink became curious to meet Mettatime, and that's when Pen decided to bring him to meet him.
They were in the center of Serentime when they reached a circular dome structure that glowed blue and had a gold tower in the center of it that reached up twenty stores and was only three feet thick, with a stand of gold protruding from it on each floor. Pen and Ink stood before the structure, as Pen took a microphone that was attached to the glowing-blue base structure, and spoke into it,
"Mettatime. Are you up there? It's me, Pen. I brought a new friend that I'd like you to meet."
"I'll be right down, darling," a voice said through the mic.
Pen looked up at the tower as did Ink, and they saw something descending the tower like if they were on an elevator. Apparently the stands on the gold tower act as an elevator, and down came Mettatime. He jumped down from the top of the large dome, as Pen placed the mic down to greet him.
Mettatime looks like Mettaton in his second form, although there were some modifications. His hair was still black and covered over one eye, while his other eye, which was blue, showed. His arms and neck were black besides his legs that were purple, while his face was gray with three black screws above his eye. His chest cavity that had a meter gauge on one side was pink, while the stomach cavity that contained a yellow soul was green. His boots that reached just below his knees were blue, as well as the cuffs of his white gloves that were hexagonal. He also had mechanical blue wings that were closed on his back, and an extra purple mechanical piece on the back of his boots.
"Why hello, Pen! I haven't seen you in a while. You've been busy with the written worlds I presume?" Mettatime asked, taking her hand and bowing his head respectfully to her.
"Hello Mettatime, and yes, I've been quite busy as of late. But I'm back, and I brought a new friend for you to meet," Pen said, giving a curtsy to him, and then he released her hand.
"Ah, yes. I'd love to meet he-" Mettatime cut his sentence short when Pen gestured towards Ink and he saw him.
"Oh, Ohhh! Hello darling! I'm sorry, it's just that usually Pen introduces me to a Curtain when she calls me over the mic, and I assumed you were one. My mistake. Nice to meet you," Mettatime said, shaking hands with Ink.
"Heh. That's alright. Nice to meet you too, Mettatime. I'm Ink." Ink said with a smile.
"So, have you been to this world before, Ink? I think I've seen your face before when I was observing the other worlds," Mettatime said.
"I haven't actually, but wait, you can see other worlds?" Ink asked.
"Why yes, I can. This tower here is what I use as a receptor so that I can see into other worlds, and this one as well. I keep watch to make sure my world is safe, and that other worlds aren't trying to harm this one, especially the dark void with those nasty creatures that come here in the Empty Lands," Mettatime said.
"Wow, it's almost like a beacon," Ink said, looking towards the tower.
"Indeed. So, since you know of this world, are you likely to visit often? I can make a room for you in Living Quarters if you'd like. Of course, I'd prefer if you worked at least one day in Carnifair while your room is being built," Mettatime said.
"Huh... I'll consider it. Thank you Mettatime," Ink said, with a nod.
"Of course, darling. It's what I do," Mettatime said.
"We're going to hang out here for the rest of week, so I'm sure if he wants a room, he can work afterward," Pen said, and Mettatime nodded.
"Well thank you for meeting up with us Mettatime. I hope I didn't take too much of your time, I know you're busy," Pen said.
"Not at all, darling. You know I love having you over to visit me. Oh! Though I seem to be receiving a call from someone at the moment. I'll catch up with you later, dearies. Have fun in Serentime!" Mettatime said, as he flew up to reach the top of the tower.
"He can fly?" Ink asked, surprised.
"Yeah. His boots have an anti-gravity rocket infused in them. It's so cool!" Pen replied, excitedly.
"Heh, yeah. You seem like you'd want a pair," Ink said, smiling at her excitement.
"Well, yes actually… you know, a Curtain has the ability to learn how to fly, but… I apparently can't. I realized not too long ago that I don't have that ability and I've felt a bit… left out I guess," Pen said, looking downward to hide her disappointment.
Ink felt bad to see Pen feeling down, and he decided to distract her for now, as he placed his hand on her shoulder.
"Hey, how about you show me more around Serentime? I'm sure there's still a lot more places to see. And who better then someone as cool as you are to show me," Ink said, and Pen looked up at him with a smile and nod.
Pen showed Ink where a purple lake was that had lilies and plants growing on and around it, and even pink and white froggits hanging around in the water. There were blue and yellow lights emitting from neon roses that also grew near the lake that bathed it in it's soft glows, and also various small lakes along the pathway that had various colors and structures with different monsters and humans hanging around each one. When reaching the last lake and being tired from all the walking, Pen and Ink decided to say their goodbyes until the next day.
