Paradox Space

The story of Homestuck and HM-1:NCAA takes place in the so called "paradox spaces". The paradox space includes variety of different universes, sburb sessions, and the furthest ring.

Universe D
The troll race of HM-1:NCAA lived in universe D, in an unknown named planet. Unlike in homestuck, the troll race is not extinct, though it should be noted that when the trolls played a Sburb like game, their planet and the other trolls in there were killed off due to The Reckoning, but they managed to secure a matriorb to the end, and then resurrect their race. They also managed to work together in peace, and only few of them were killed but those who died, were resurrected with dream shenanigans, which connect to kissing the body to turn their dream self into their awoke-self. There is other trolls mentioned and "seen" in the story, but the 12 main troll characters are the ones who are focused on the most, when compared to any other trolls in Modernius. After they won Sburb, they claimed the prize of making their own universe. They made the Universe E, where they currently live in, in the planet called Modernius. Note that the Trolls and Humans actually live in the same universe, but on different planets. The fact that they made Universe E where Redzly lives in, is a reference to the fact that he didn't live during the times where the trolls played Sburb, so he doesn't tell about their Sburb journey in the story, unlike in Homestuck, because even though he is actually the author of HM-1:NCAA, in-story he doesn't know at least about all of the events that took place in Universe D. Its not never really told who or what made Universe D, but a possibility is that Universe D was made by Caliborn or Calliope in an another timeline in Universe C, where they managed to work together and win the game of Sburb. Additionally, Redora mentions many times throughout the story that he knows of other timelines and universes where other Trolls lived, and of their mistakes they made, but its not confirmed is there some actual connection with Modernius and Alternian trolls, expect the fact that they are part of exactly the same race, just in different universes and both made by different sburb players. However its also possible that the Horrorterrors made 2 different universes, where Trolls live in.

Universe E
The Human and Troll races live in Universe E, but in different planets. While Universe E and Universe B are different, the both human planets are equal by real-life concepts they have such as celebrities, countries, languages, companies, and other such concepts. While this is a thing put in the story to joke and write the story using earth things like in homestuck, Redora is known for being the leader in most operations, such as when they made universe E, and he is also a "Master Time-Warper". He has studied human culture both from Universe B's and E's human planet, and he has strong knowledge of humans and other concepts from other universes and timelines, which can have something to do with equal similarities that Earth E has with Earth B from homestuck. The main human kids are also from Universe E, and so is Redzly and his younger self.

E1 - Pre-Scratch
In E1, the only main characters are Redzly and his past-self Reddy. E1 is the Original pre-scratch timeline, where most of the stuff that started the plot of HM-1:NCAA coems from. When Redzly used time shenanigans to summon his past-self into his current timeline, they soon after started playing Sburb together "out of boredom". Nothing much isnt know from their Sburb session, expect that they managed to beat the game succesfully. Redzly mentioned that he summoned his past-self to his current timeline in the first place, because having your past or future self as your best friend is one of the must-have things in his view. When they completed Sburb and made Universe F, they afterwards wanted to activate the Scratch sequence for fun even though they won, because Redzly had the idea that he could bring their planet back, and also have Universe F exist, so he could have double the reward. However when they activated the Scratch sequence, E2 started. It should be noted however, that when E2 starts for the FIRST time, that is not when the story and narrating of HM-1:NCAA starts yet.

E2 - Post-Scratch
In the first E2 which came to exist after Redzly and Reddy activated the scratch sequence, the human kids Autumn, Leviko, Lilly and Subu started to play Sburb. However this is not when the story starts and when its started to be narrated, since the story actually starts in the first loops E2 universe. In the first E2, Autumn was born biologically by their parents and they were just a human. Since they activated the second scratch sequence, its presumed that they didnt win sburb. After this, the E3 known as Loop-scratch started, because the Post-scratch players aren't supposed to activate a scratch sequence. After the first E3 happened and then at some point the Loop-scratch players also activated the scratch sequence, and for the 3th time in Universe E, they started the "Scratch Loop". Its not known what happened in the second E1, but after a Scratch Loop happens, its destined that in every scratch variant a scratch sequence happens, so then the second E2 started. And that is when HM-1:NCAA's story and narrating finally starts.

Scratches
In Homestuck there is so called scratches, and every universe always has a pre-scratch universe. If a universe has a post-scratch version such as Universe E, the Universes in the list of the respective universes universe's are known by E1 being the pre-scratch and original version of the universe, and E2 being the post-scratch and second version of the Universe. HM-1:NCAA follows how the scratches work, in the same way as Homestuck, however HM-1:NCAA adds a new, third scratch variant, known as loop-scratch.

Pre-Scratch
Pre-Scratch is the Universes first and original universe, or which could also be seen as the Universes first and original timeline. As mentioned, its the original variant of the universe, so everything that exists and happens there, is always a part of the Pre-Scratch variant.

Post-Scratch
Post-Scratch is the respective universes second version, and it can occur if a "scratch sequence" is activated correctly. A scratch sequence can always be done to start the Post-Scratch universe, if one of the current sessions players is the aspect of time. Scratch is a special system for the time aspect players, which allows them to start the session over again, but in an another variant of the current session players respective universe, which is known as Post-Scratch universe, or by the universes name, but as the second one, as an example Universe E3 being the post-scratch variant of Universe E, however its E3 for a reason, and not E2. In the post-scratch variants there can be multiple differences, but something is always different. Most of the time, the original universes players and their guardians are swapped in place. The post-scratch players usually may also have different aspects that the pre-scratch ones. The post-scratch players are still related to their guardians in a way or another. For an original example, Dave Strider is his bro's guardian in the post-scratch variant, unlike in the pre-scratch universe where his bro is his guardian. The Surnames stay the same most of the time, but the first names are in all seen examples and universes, always at least originally the same, in both pre- and post-scratch. It should be noted that for an example, post-scratch Dave is not actually the pre-scratch Dave, but rather his post-scratch incarnation, that has heavy similarities. This is true for all pre- and post-scratch characters. The only expection would be Autumn and his post-scratch version, as well as his loop-scratch/pre-pre-scratch version. Autumn and his 3 other self's are all exactly the one same person, but who just lived different lives which changed their tastes or outfit looks, depending on how they preferred to live their life's like. Autumn and his 2 other self's are all kids in their respective pre- and post-scratch universes, expect his 4th one who is him but Adult, and also the true original Redzly, from the loop-scratch/pre-pre-scratch.

Loop-Scratch
The Loop-scratch is a third scratch and universe variant, introduced in HM-1:NCAA. The Loop-scratch is created, if the Sburb-session players in post-scratch manage to start a scratch sequence. When post-scratch players manage to activate a scratch sequence, they try to make a post-scratch variant for their current universe, however since the post-scratch variant already exists, which was made by the pre-scratch players, this leads to the so called loop-scratch variant of the universe being made, looping the universe in scratches for nearly infinite loops. If the loop-scratch players activate an scratch sequence once more for the universe, this truly starts a "Scratch Loop", which is one of the main plots in HM-1:NCAA. When a Scratch Loop is started after the Loop-scratch players activate a scratch sequence once more for the third time in the universe, the universe starts back in the pre-scratch timeline, in Universe E's example E1. This is when the Loop Scratch has happened, and it means that the players are destined to activate a scratch sequence, in every variant of the universe. This means that there will be total 3 scratch sequences activated in the universe before its reset back to the pre-scratch variant, in this example E1, and this will continue for eternity as the players are destined to keep activating scratch sequences in every variant as mentioned before, after the Scratch Loop has happened.
