Making up the space in the universe are several dimensions, split up by barriers that prevent the dimensions from clashing together. However, these barriers are not keen on keeping up with protocol, and sometimes something from one dimension will fall into another. These misplaced things are called anomalies , as they are not supposed to survive the conditions that reside out of their home dimension. Indeed, sometimes an anomaly can adapt to living in an outside dimension, and these adaptive anomalies are titled invasive species . All in all, anomalies are a natural occurrence of chaos meant to stabilize the universe, but frequent exchange of anomalies must be monitored. Constant traversal between dimensions or negligence for portals can lead to dimensions clashing, and fusing, into new existences.

Due to the many dimensions in the universe, the Dimensional Spacetime Protection Agency has categorized these places into eight types:

Realms, dimensions with habitable space, including planets and biomes.Realities, dimensions with hostile space, but specific planets or biomes which can contain life.Zones, dimensions with habitable space but no planets, just an endless stretch of various biomes.Spaces, dimensions with one or more megaplanets, including endless stretches of biomes, typically surrounded by hostile space.Worlds, dimensions with one or more megaplanets, typically surrounded by habitable space.Planes, usually confused with Zones, but having one specific biome as opposed to many.Lands, usually confused with Zones and Planes, but are surrounded by hostile space.Voids, dimensions with no natural planets nor biomes. Space can be habitable or hostile.

These eight types are known as Major dimensions. There are also Minor dimensions, which are smaller dimensions typically created by entities within a dimension. Even with categorization, the names these dimensions have may not correlate with the type of dimension they've been assigned.

Another thing of note is that these dimensions do not always follow the laws of another. For example, the randomized effects of the Illuminated Reality are an altered physical medium of the Realm of Polygons, which, in the latter, has violent gravity despite no definite mass governing such a property. If you plan on becoming an anomaly yourself, you must accommodate for the dimensions you will visit, and whether the laws of your world will match with another.

The fluctuation of time has caused certain events to be monitored. It's these events that help the Dimensional Spacetime Protection Agency, as well as all beings, determine when things happened in the history of the universe.

A really long time ago, nothing existed. Absolutely nothing, it's not even accessible by time travel. Then, a moment later, this fact was subverted in the most violent way possible. Essences built from nothing forming into time and space, dimension, everything imaginable and unimaginable coming into existence at once in the simplest form. Many mortals like to believe an omnipotent being triggered the creation of everything, birthed the universe, but the Polygons know otherwise... and they refuse to tell anyone. This event is called the Mother Event, occurring at the beginning of the timeline.

Five billion years after this, a group of Polygons were born to the universe: Thesis, Expy, Times, Divide, Plus, and Minus. These sixtuplets are not the beginning of their kin, but they are important in their species' history, being the first who act instead of watch. Minus, especially, has a mean streak for appearing in other dimensions and driving mortals to madness. Expy, however, is also the first Polygon to die at the hands of a mortal. The beginning of these sixs' existence is dubbed the Genesis of Algebra.

Two billion years past this is an event of the Old World, called the Rapture. It is not a pleasant time, as the Humans of Earth looked up to the bright light in the sky. A hand descended from a break in the clouds, and suddenly, there were screams. Those that followed a specific religion were infected, and became beings of purity, known as Saints. Those that were not taken into the ether panicked in fear, and pooled their resources into finding a way to retrieve their lost kin. This, inevitably, would lead to the Humans' universal conquest.

The Morality War is a five hundred million year war between the Angels and Demons, which began shortly after the Rapture's 50-year anniversary. Time cataloged in this time frame is either stated at the beginning, middle, or end.

Around three million years before the year 2000, a Xoman named Tremophy harnessed the power of an infant Polygon, and gave its power to him and his four friends. This is the Birth of the Universal Guardians, beings that claim to protect the universe and establish order, but in reality just issue control. Every ten thousand years, the Universal Guardians roll out a new set of workers, which are called Circas. Time after this event is catalogued in Circas.

The year 2000 in Humanity's Reality's Earth marks the moment this planet would change permanently.

To categorize these various dimensions and beings, the Dimensional Spacetime Protection Agency has developed a cheat sheet.

For dimensions, this is:

Type : any of the types discussed in Dimensions, which includes Realms, Realities, Zones, Spaces, Worlds, Planes, Lands, and Voids.
Safety : how safe the dimension is for its inhabitants and anomalies as a whole, categorized into Welcoming, Plausible, Cautious, Hostile, and Lethal.
Comprehension : using the comprehension scale rating system, ranging from 1-10 with 1 being the most easy and 10 being the hardest.
Naturals : natural sentients that have evolved within the dimension.
Invasives : anomalies that have made a home, and have possibly evolved with it.
God : the name of the Hermi-One(s) that were born with the dimension. Integral to the overall history and personality of the dimension.

The Sentient beings of the universe only have to deal with their Comprehension ranking. Those with a level of 1 will be the easiest to understand, with 10 being the most complicated.
