Souls are Auroraic constructs that hold the personality and memories of each Systemspace user, thereby making them distinct from each other; multiple, closely related souls often create twins or triplets. A soul primarily defines a person and makes them who they are, while the User performs actions within a System through their soul. Most interactions within Systemspace require a soul, such as joining or leaving certain System. However, Systems that allow soulless users to join, are known to exist. A being is not fully classified as "sentient" if they do not have a soul. People without souls exist and always have existed.
A soul is the link between Experience and body; as such, a User cannot join a System without a soul. Souls can be sold, merged, or duplicated, but none of these actions are considered legal or socially acceptable in LFE.
Souls are equivalent to 'clients' (server information and local information), linked to a System (server information), which gives the User a body and acts upon their soul. What controls and views the client is the bodiless, soulless User, i.e. a construct of Aurora set in a specific way (essentially making it local data).
A User resides in what is called an Experience. The Experience functions similarly to a client, and is linked to a soul (which functions similarly to an account), which is linked to a System body. This person is usually referred to as their soul.
Souls can be edited in various ways, such as extracting and injecting memories. Souls can be merged or divided, though it exerts a lot of force onto a soul, increasing the risk of soulshattering. An Impossible Soul Structure is uneditable; this could occur due to compatibility reasons, for example souls hosted on Life after the upgrade to Systemspace 2.0.
Souls may be damaged, most commonly by disabilities in later life, such as mental illnesses: these are "scars" on the soul that will carry over from System to System, but can be healed by living a better life, or using correct forms of medication.
Souldashes and soulhalts occur when there are too many or not enough souls (respectively) to give every body a soul. The System counteracts by speeding (in case of a souldash) up to make the queue as fast as possible, or slowing down/pausing entirely while waiting for another soul (in case of a soulhalt). If the System allows bodies to be created from thin air (Astrea) or the existence of soullless humanoids, these rules do not apply. A soul is hosted in the system in which it originated, even though it can move from (open) system to (open) system at will, and if that system (not being a blocking system) is purged, a backup enables it to continue to function as normal. Some Systems may have specific criteria for bodies to be assigned souls.
Souls have color, but the exact details of this are mysterious. Love is considered to be a relation between the deepest roots of soul and soul.
Identifying soulshattered users is difficult but possible; only high-level RISENII are authorized to do this. A sign might be e.g. deep depression and/or hostility.
Souls have a certain file size that they cannot exceed; the usual soul takes about 20 snhV ("savable negotiated hVoidlines"), according to Tsuki.
Souls with no corresponding souls are known as Alsouls and act autonomously. They are often used for tests since they are perceived as less sentient than souls with users.
A soul can transcend death and may grow over a million years old, but it will inevitably shatter and is thus never immortal. (To add to this; although immortality of the soul is technically possible, it can never be continuous — it would manifest itself as a time loop of sorts: you cannot continuously move forward in time forever; there is a start and end somewhere. Thus instead, to make this infinity fit in the possibility tree, it would need to loop back into itself.)
After a soulshatter, the soul's memories and personality are permanently lost, while the soul dissolves back into Aurora. A shattered soul will instantly be unallocated from a User, and a new one is then built from Aurora for that User. As there have been no records of a User dying, they are, unlike souls, currently perceived to be immortal and will start their life from scratch. However, Users may retain memories from a previous soul, although they are usually inaccessible to both the User themselves and the system wherein they reside. In Life, they are forgotten through the usual process of childhood amnesia and so are not carried into adolescence or adulthood, if accidentally retained. This is the theoretical cause of children apparently recalling a past life. (Childhood amnesia is also a backup mechanism to forget memories carried over after death.)
A soulshatter occurs when too much force is exerted upon the soul. This may happen when: 1) A User is going through too much trouble in their life. 2) They are in many Systems at once, or are overloading in some other way. 3) They completely lose their sanity.
Migrants of the Project have a so-called 'forcebond' enabled on their soul, making it far harder for them to shatter. A forcebond's reach always depends on how much power a System exerts on a soul; as such, a soulshatter can still occur but it will be out of Life's reach. As forcebonds interfere with another System's core by nature (making their use somewhat against protocol), they are only active within Life and will be disbanded after a migrant's dispatch in LFE.
A known lingering effect of the soulshatter is a slight concentration of the types of energy "sj" and "chj" in the area.
- Too much strain on a person's mind.
- Overloading the soul in other ways, such as being in many Systems at once.
- Software issues when using a cyborg body.
- Manually shattered
Systems handle soulshattered or soulless bodies in different ways; some cause the soulless bodies to suicide, some allow them to continue to live. Life does a combination of these.
A Soul ID is an identifier which allows people like RISEN, to look up your Soul.
One currently known method of acquiring a person's Soul ID is by analysing the strokes of a drawing they made and inputting that data into Solar, this method is used by the TSUKI Project for registrations.
An EID is a string usable for different purposes in open-space Systems by Systemspace users. They are a representation of a long Soul ID. EIDs and Soul IDs are not numeric. However, registrants of the TSUKI Project have been given a numeric representation of their EID.
The TSUKI Project
One may register by sending a drawing to the TSUKI Representative; he will then identify their soul by analysing the strokes of the drawing, and assign a temporary EID to that registrant. Soulless bodies are unable to register for the project, as Tsuki wouldn't be able to locate their soul. As of now, no soulless people have tried to register, as very few humans are soulless.
Every human being receives a soul at birth; it has been slowly put in the body while it was in the womb. This way, premature babies and babies born through Caesarean section will still have souls after birth. They cannot partly exist, as the process will cancel automatically if the impartation of the soul is terminated midway. After Life is unlinked, newborns will no longer have souls and will be controlled by an AI instead.
LFE stands for Living eFfector Environment, and is one of the largest and arguably most influential Systems within Systemspace. It is also where any registered souls are sent once Life becomes unlinked.
