The Terumverse is a massive Multiverse that consists of many timelines, stripped from symverses to create the best group for the "Terum Project." Each verse is one single timeline, separated from other verses unless it is an "Anomaly", or a being from said verse is capable of traversing or understanding the existence of other verses.

# Undertale

The classic. Undertale is the primary verse within the Terumverse, being the root for all other verses to grow. Based on an alternate Universe of the Prime Earth, it follows the story of a world where humans and monsters once co-existed, which soon ended following a great war that led to the latter race getting trapped underground. The timeline follows a True Pacifist route of the Universe, one in which a human under the name of Frisk had helped all the monsters escape the risk and learn to co-exist with humans once more.

## Dusttale

Dusttale is an alternative timeline of Undertale, following a story where a singular character went on a brutal rampage prior to the human's rampage. There are two timelines for this Universe, strangely enough.

### TL!Dusttale

TL!Dusttale is the variant of Dusttale in which it follows a similar premise to the original. It follows a Universe where, after countless deaths, Frisk finally murdered Sans, but reset afterwards. With all the déjà vu from each kill, each time he had to kill the same human, he had enough recollection of events to know what would happen if he let the rampage continue. So, while reluctantly, he had taken away the lives of every monster in the Underground, leaving nothing for the human to collect. Separated entirely from the concept of death, he roams completely sane, but devoid of all remorse.

### Dusttale+

Dusttale+ is the alternate timeline of Undertale where the premise itself changes, though the concept remains the same. Flowey, an already apathetic flower that constantly is aware of every timeline, gets an idea they hadn't tried before. While they had killed everything before, they hadn't done it in a way that required another. With Frisk starting genocide in the Ruins, Flowey had gotten the idea of killing everything past The Ruins before Frisk could even get to it, leaving them devoid of LOVE, and instead forced to face off monsters such as Asgore with not enough distance from killing itself. And, of course, this didn't include Flowey himself in-battle. That was entirely different.

## Killer's Timeline

Killer's Timeline follows an alternative timeline of Undertale, one where Flowey had once again taken the initiative to commit mass murder, only under the hand of Papyrus this time. Flowey had taken control over Papyrus' life, manipulating him to become that of a clueless murderer. Papyrus, given that he wasn't innocent, clearly knew the consequences of death. However, when fed so much delusive memories that came from fake lies by someone he simply couldn't not believe, it drove him down a path that slowly distanced himself from the lives of others, and soon himself.

## Outertale

Outertale is a friendly, beautiful Alternate Timeline of Undertale. This is a timeline where the monsters had been abandoned to space, where they were left to supposedly die. However, following lots of technological advancements through both human and monster races, they had found a way to survive within space. Frisk, a young child, had went aboard a space station and ventured out into the vast expanse of space to find the monsters.

# Underfell

Underfell is an alternate Universe of Undertale, being heavily influenced by its stem and following a similar story. However, the major difference in this Universe is the theme of "Kill or Be Killed" is extremely prominent within the underground, to the point that even monsters are threats to other monsters. This verse is extremely cruel, and is possibly the most dangerous for any regular being. Constantly at each other's throat, a cruel monarchy with a medieval guard leads any human to a world not of hope, yet instead destruction. Determination isn't enough to survive.

# Underswap

Underswap is a strangely recognisable take on the general Universe of Undertale, consisting of the exact same characters, though forced into alternative roles that are considered unfitting. Strangely enough, it works well. Little personality alterations are found, though every character is within a different setting. It is actually quite beautiful, in perspective. Many locations share similar alterations, though still share the same feeling of potent beauty that the original had.

# Alphatale

Alphatale is a Universe that is similar to Undertale through the means of setting and premise, though entirely different in almost every other aspect. It follows a storyline where the war had taken a very, very different route, leading to an oppressive government that soon expanded past the simple boundaries of timelines. This is considered the first anomaly.

# Underhell

*Main article: Underhell*

Underhell is an Alternate Universe of Undertale where the events have entirely warped and shifted to that resembling various religions and mythologies, starring the two primal races of angelics and demonics. In this Universe, the Underground is replaced entirely with Hell, and various cruel afterlifes that propose a similar function to hell. The overground is instead a heavenly realm, and it is possibly considered the most purest place in the entire Terumverse. Each main monster replicates one of the seven deadly sins, and it is the one Demi-Human's job to purify Hell of those sins, one way or another. They serve no limit.

# Trivia
