Existence

Existence is a plane composed of an uncountable number of varied dimensions. Beyond Existence is an uninhabitable region known as the Outside. Dimensions are ordered by a small series of patterns known as the System. Virtually all dimensions in Existence are unaware of the outermost multiverse, although some dimensions are organized into internal multiverse clusters. Most beings are incapable of interdimensional travel; upon an individual's first instance of traversing dimensions, they will experience a handful of a wide range of effects, including total destruction for some of weak will. The effects an individual experiences are contingent on their particular makeup, and there is no consistent way to determine the severity or nature of the event in advance. As a result, interdimensional travel is dangerous for most beings to attempt.

Dimensions
There are two types of dimensions in Existence: Source and Path. Every dimension is comprised of a single Source, which is the base form of the dimension, and a virtually infinite number of Paths. Each Path specifies one possible timeline for the dimension, each delineated by different choices, and without the ability to deviate from the route. The fate of a Source, however, is ambiguous and may be changed. Path dimensions do not include drastically different "versions" of a dimension, which often are a unique Source. Most dimensions in Existence, with exceptions, abide by the same basic laws of physics, logic, etc.

Composition
There are deeper fundamental units that compose Existence than the multitude known by most dimensions. All fundamental particles like quarks, gluons, electrons, and equivalent are composed of philotes. The deepest layer, Code, is the basic foundation of all things. Triggers, when they existed, were able to destroy Code at will.

Systems
Existence has undergone a number of System changes. The background and details of each System vary. The first known System was known as the Ancient or Autonomous System. It regulated important functions of Existence automatically, including entropy, the lifespans of dimensions, time, laws, etc. At some point, the Autonomous System deteriorated into the Anarchy System, in which Existence devolved into chaos.

The Nobility System
The Nobility System first appeared when a group of powerful beings rose up and reined in the Anarchy System. They began regulating the fundamental order of dimensions, but they also ruled Existence as an aristocracy, directly managing dimensions. They became complacent over time and ceased involvement in affairs of Existence, allowing it to deteriorate once more. Soon, a group called Tier Five arose. With a cabal of strategic recruits and the help of King, the leader of the Nobility System, Tier Five overtook System Control.

The Tier System
The Tier System is also a classification system. Tier One consists of animals with no intelligence. Tier Two consists of intelligent beings. Tier Three consists of intelligent beings with a form of 'ability.' Tier Three humans would be known as 'superhumans.' Tier Four consists of interdimensional beings, those who have the ability to travel between dimensions without the aid of a specific item. Tier Five consists of hand-selected beings with authority over the System. Some beings deny the existence of Tier Five and consider Tiers as little more than a useful classifier.

A hotly-debated class is known as Tier Zero, which consists of nonliving entities, including those that appear to be intelligent.

The Balkan System
The Balkan System is the result of unbounded Gears of Existence, but with lingering dimensional patterns from previous Systems. It has the unique property of enabling any being to acquire System control over a dimension or collection of dimensions known as a 'territory.' If two beings dispute the rightful ownership of a given territory, they may settle the dispute through a pre-agreed resolution method, including combat. Territory ownership grants limited System authority while the owner is located within the territory, including significantly enhanced power, perfect dimensional locks (complete rejection of disallowed entities), and increased awareness of the territory's state. If any being obtains ownership of more than 50% of territories, they are capable of rewriting the System completely. As such, strategic territory claims have become commonplace between those contending for System control.

Governments
There is a small number of governments Existence with interdimensional influence. The three commonly addressed in Myriad Reality are relatively new, established within the last few years by or as a result of members of the group. The Interuniversal Alliance, once the Intergalactic Alliance, is associated with Sven and the Big X. The Existential Democratic Bureau is associated with Shinji. The Crimson Armada is associated with Kirina, formerly led by Drake. Other interdimensional organizations exist with varied goals, such as the Encyclopedia of Existence.
