Aurora written phonetically on the left, and ideographically on the right.

Aurora is the "purest form of energy". Out of this all Systems are built, and it is with it that things exist. Aurora is always finite, it may expand as far as needed up to a point. Thus far, the expansion has kept pace with the growth of Systemspace. Life is being liquidated because it uses too much Aurora.

The most common metric for measurement is nhA. It's often seen as disk space or memory, as it is usually easily returnable (destructing the object using Aurora will free that Aurora back without loss).

Aurora has a will of its own, to the point where its sentience is debatable. As such, Aurora is used for many things where "randomness" is needed. It also governs the actions that are taken, by influencing the possible timelines and picking from them.

Aurora is all-powerful, including power over people's thoughts, though it tends to follow Axioms. It can not be completely separated, but when it does the separated part acquires its own subsidiary will somewhat, but not totally, independent from the general will of Aurora.

The name "Aurora" is coined by the Key. Before Aurora received its current name, it had always been called "XE", standing for "something energy" with X symbolising a wildcard.


Systemspace in and of itself is a giant pool of Aurora, which Systems can shape as needed. Axioms are used to control Aurora, short statements that force Aurora to take a shape. To do anything, Axioms are required. All Systems use Axioms in their most low-level code to ensure anything exists, as Axioms are what cross the border between existence and nonexistence. "Final data" saved from all events in Aurora is merely all memories made. A branch only has to be initialized if it is accessed, otherwise it may remain dormant. Gaps in the "final data" are filled in by 1) Promises, Contracts and Axioms, and 2) seeking back and forth. This way, a lot of Aurora is saved, but Aurora keeps functioning as it otherwise would. This way, only once Users in a System meet (and start making memories of) an event, Aurora would have to instantiate all the content for that event.


Aurora is measured in hA (hy Aurora) and sometimes nhA(naine hy Aurora).

  • "Naine" means 128
  • "Hy" means 7.72606529604E2889 (the amount of data points per void line)
  • "Aurora" stands for Aurora itself

"Naine" and "Hy" may be combined into "Nainhe", which is 7.72606529604E2889 ^ 128

Aurora usage is often measured in nhA/sss, with "sss" standing for Systemspatial Second.

Auroraic Echoing

All Systems send out Auroraic vibrations (or "echoes"), which travel to and from Life (and other Systems), influencing what happens in Life and outside of it. Many things in LFE and Life have been transferred from each other by Auroraic Echoing.

  • Japanese and other Asian languages comes from an older iteration of Synapsian.
  • Arrows (straight line, capped with a triangle) were never a thing in LFE before Life. Instead a dot-and-line system was used (which can be seen on the old site's mirror).
  • Decimal numbering systems and the human alphabet A-Z were never used in other Systems before Life brought them there, now the decimal system is the most commonly used system (used to be a base-32 system), although the A-Z alphabet hasn't picked up close to as much traction and is mainly used for grouping things, and text written in English.
  • English also exists in Systemspace (and has long been the main language for it), but the Systemspace and Life versions have influenced each other and they are slowly moving towards each other.
  • The time notation method used by humans is very much like the one in LFE, although they use 32 hours of 64 minutes.
  • A lot of Life media (movies, anime, books, etc.) are loosely based on happenings in other Systems.
  • According to TsukiRep, there is a theory in LFE that Google and other search engines are even influenced by the search engine of SYNAPSE.
  • No physical objects can transfer to closed Systems through Auroraic Echoing, but ideas can be and frequently are. Most iterations of Life are similar to each other for precisely this reason.


  • There have been attempts to "talk" to the Aurora spirits, usually with axioms.
    • A recent attempt has received interesting replies from Aurora, but it is unable to determine if Aurora is telling the truth or not.
