You enter the very large building. And as if it were to make sense in Euclidian space, the interior is also very large. I neglected to mention why you were asking about the building. You are quite piqued by thoughts of very large or very small things. That's kind of why you chose to do the map design for the game you and your friends were planning on making.
Hehe, looking back at it now, that fangame is probably never going to be made. I mean, you and all the other people who had anything to do with it are going to play this game, and from what you can tell, the game is very prevalent in your future lives. It's a shame too, you four put so much work into it. You remember spending countless nights plotting out the maps of the potential game with the sprites from Mew Mew and Suki. You actually got well into the 2nd part of the game's maps before you kind of just stopped.
Oh, what's that, you want an explanation of Into The Underverse? Ok, a few years ago, as in 2x2x-2, you, meowrage, sent an email to your friends about "hey, remember undertale?" and stuff like that. Then, like a day after that, Syb sent an email RP-ing as Papyrus. You sort of remember it being about him going across the world on a journey of sorts. Then, Mew Mew RP-ed Toriel replying back as though it was the true-pacifist route. You remember feeling a rush to RP Sans because you knew that Suki would really want to do Sans. You RP-ed something about how life was without Papyrus and then it continued from there for about 2 weeks.
Then, Syb started what seemed like a novel sort of thing and wrote instructions of what the characters were doing and saying. You jumped in and it went back and forth for about a few more months. Though, towards the end of it, Syb was really writing most of it.
The story was split between 4 parts. Although the original idea wasn't, it eventually became that. The first part followed Papyrus and Sans' correspondence, then their birthday where Gaster showed up because of baba yaga (that was a very silly thing that actually happened in the original) and Gaster shows his two sons their ungodly powers. Sans could form matter out of thin air, and Papyrus could quite easily traverse the multiverse. Eventually they made it somehow to Deltarune's universe (I forgot how they did it in the original, the rewrite had them going on a journey to vanquish Jevil because of Papyrus' mom???).
Part 2 was the journey throughout Deltarune and a lot beyond that. It saw Papyrus, Sans, and Frisk waking up in their deltarune counterpart's rooms. Frisk decided to follow Kris because Chara (who was inside Frisk for some reason) felt an alternate version of herself in Kris. Sans put his counterpart in a bonema (bone coma) and Papyrus befriended his counterpart. The now 4 of them go off to follow Kris, then they all team up with Susie and Kris, then Rasiel (not ralsei, I hadn't played deltarune at the time), and the 7 of them make it to Jevil who nearly defeats them all until metaton's dopleganger, Not-A-Tem takes them outside of the imagination world. The gang hangs out with alphys until Jevil takes over Not-A-Tem and then breaks free, setting all of them into an anime version of the Underground (don't ask me why I thought that was a great idea). They then go through the Underground while Susie pelts them all, and they pick up all their teammates along the way where they were in undertale or where their counterparts were. They pick up 3 new teammates, the bird (Syb but also me), Red (The dog, "meowrage's" self-insert) and Mew Mew (can you guess who's insert this is?). They eventually make it to the hotel where Frisk does some heart-memories (...) and then steals Susie's axe and puts her onto their team. Also Kris then kills Rasiel, but not really, but also, something? Then I think they went to the Gaster door, and somehow made it back to Deltarune. Then the people from Part 3 show up.
Part 3 was slightly simpler. Alphys, who had been doing stuff in the undertale universe, gets notified by Muffet, who was Papyrus' girlfriend, that they all were in some alternate universe. Alphys then somehow makes it into an Sans' mind in the genocide version of the game and he kicks her out, and she makes it to a train station with a few of the alternate versions of sans and Papyrus Papyrus had found in part 1. They then make it to a french universe and then fight Red the dog, and hatch a dragon egg, then they fly it almost to Jevil, but then Not-A-NAT (Not-A-Not-A-Tem) shoots the dragon or something. Also Syb's there for some reason (the train is a metaphor). And Flowey's here, and he gets visions of Jevil fighting Kris' Chara, or something. Then they free all the temmies from enslavement, and then they destroy all of Jevil's robots that he got from french Gaster. Then Not-A-Tem plainly, allows them to take the train to the end of part 2.
All of them now take the train to Jevil's mansion and then their train is busted because some darkener was attacking them, or something. Then they go through the mansion, then do a bunch of puzzles, and Undyne, who was Jevil's defense attorney (>W> ahahahahahaha) shoots Jevil, but oh no, Frisk takes his place, and then Frisk's soul goes to Chara. Several years later, Chara is doing her normal thing when Syb's Sister, Bys, goes up to Chara, and says, "you know what, this is all an illusion, you're dreaming this" And then she shows her (chara) all her memories from before she was a spirit, and how she and her brothers were all chosen to create a multiverse. Sans created the universes, Papyrus oversaw them all, and Chara was the one to reset timelines using her saving powers. Then, on the night of her gaining all her infinite duties, she fled to the underground, and then Jevil gave her a knife to kill herself, relieving herself of all her duties. The multiverse people weren't happy with this, so they created a second multiverse nested inside the other multiverse, and just said, stop making universes. Achra (kris' Chara) was the Chara in the alternate multiverse, then she became aware of her own petty existence, and condemned all the people who made her to pretty shitty existences. Chara then wakes up whole with Frisk. The two souls sharing one free all the friends from parts 2 and 3 from their personal delusions created by Achra to harness the power to infect the rest of the multiverse (consisting of all other indie games) with her power. Then the gang finally fight Achra at her final power, then every metaton formed one big metaton and destroyed Achra's giant screen. Achra then almost kills them all, but then sans throws her into the shadow realm with Frisk and Chara. Achra then attacked Frisk and Chara stabbed her in the chest, thus ending the story.
Ok, I can admit it, Into The Underverse was very very very very very very very very oh so very silly. Every part that can remember has some silliness that I can't even describe. But still, it was my seventh grade, and also your seventh grade (meowrage). I eventually tried to write a more cohesive plot in the next year but I didn't get too far with that. And now I'm doing this.
What were we talking about- Oh yeah, buildings. PS takes you into the building and you like buildings because they pique your interest.
