Infinite Garden

The Infinite Garden is the central life simulation that is run by and hosts most of the Earthen remnants. It is technically infinite and has a self-growing and changing hubworld called the Stemspace from which the deliberate public and private simulation spaces connect to.

Description
The remnants are connected directly into the simulation via their consciousness cores. This allows the simulation to accurately simulate all stimuli and senses, creating a digital reality that is indistinguishable from the real world of biological humans. Of course, the remnants are aware of their circumstances, and can exit and enter the simulation as they please. Most stay in there regardless, as they have little to gain from being in the real world.

The structure of the Infinite Garden can be compared to a tree. The trunk of the tree ("Stemspace") is the basis of the simulation, and the simulation spaces are the branches and leaves from this core, which can be shaped to one's needs - the trunk, meanwhile, grows as it pleases and is only every touched upon by maintenance if deemed necessary for the stability of the simulation, something which has yet become a concern.

Public places
Public places are simulation spaces that are always open and public for anyone to connect to. There are a myriad of spaces, with many more being created as the whims of the simulations inhabitants dictate. Examples of public places are clubs, parks, cinemas, arenas etc.

Private places
Private places are the personal simulation spaces created by the inhabitants. They often take the form of a person's 'home', being a corner of the simulation that they can call their own. Private places are by their nature private, and one needs permission from its owner to enter.

Stemspace
The Stemspace (named so because "it sounded better than Trunkspace") is the simulation space of the simulation's core, and can be seen as the manifestation of the coding itself. Stemspace grows organically and autonomously along with the simulation without input from the simulation management. It is the subject of fascination and observation by the remnants, as it appears to be growing in line with the personalities and thoughts of the simulation inhabitants - for example, Stemspace places may autonomously grow into rooms or places that certain individuals in the simulation have experienced in their biological life. Stemspace and its growth and nature is thus often explained as a "shadow of the collective remnant subconsciousness". Because of this underlying connection with the collective subconsciousness of the remnant inhabitants, Stemspace is studied in the context of human psychology as well as an experiment of "organic programming".

Stemspace is by its nature illogical due to its digital core engine. While the public and private places are designed to conform to human perception of normality and reality, Stemspace is not bound by this and as such can grow impossible structures. It has been observed that Stemspace places can include impossible geometry and archaeology, like an infinite park, a room that loops into itself, illogically-sized buildings (whose insides are often not proportional to its outsides) etc. It has also been observed to contain "shadows" of human beings, most likely a side effect of the memories of people that remnants possess.

Stemspace is mostly safe to visit (as a simulation inhabitant simply has to wish to be there or anywhere else to come and go as they please) and can be entered by anyone. Many visit to behold strange geometry and things that were never possible to experience in real life. While there are no direct dangers to one's life, there may be psychological dangers present as Stemspace may manifest deep fears of individuals, or construct such impossible geometry that one suffers from "geometric overload" if one thinks about it too much.

Digi-earth
Digi-earth is the largest public place in the Infinite Garden, being a work in progress 1:1 replica of earth in 2092 just before the cataclysm. Even a century after, Digi-earth remains unfinished, but many known places (such as the himalayas, grand canyon, cities such as Paris etc.) have been modeled, as well as well-known landmarks and structures (the eiffel tower, stonehenge, great wall of china etc.) Some remnants elect to place their private domains in Digi-earth, sometimes new artificial buildings but also where their actual home was located at the time of the cataclysm.

Aiva's Meadow
Aiva's meadow is a place in Stemspace that manifests as a rich and lush meadow of a visually large size, but is actually "only" one square kilometre in size. Mountains are visible in the distance, and the sound of chirping birds can be heard, though no bird have been observed. Aiva spends a lot of time in this meadow, and claims that it's a construct from her own subconsciousness, saying it's a part of her as natural as her voice and memories. Though difficult to prove, it is assumed to be the case.

Siments
Simulated entities ("Siments") can be found in various private and public places. They are artificial AI constructs that often take the form of animals, mostly personal pets, but also as general wildlife in the various spaces.

Am
Am is a mysterious lady "of many faces" that has been appearing in Stemspace, and rarely, even in public places. She has been described as a young woman with a hazy lower body that obscures her legs and gives off the impression that she's floating. Her face and hair shift constantly, often while not being observed and entirely instantly. None of the faces so far have been found on record, though it is believed that they're amalgamations of inhabitants faces, merged together to create a new face. Little communication has been achieved, but when asked who she is, she simply responds with "I Am". Her voice has been described as a "chorus" with many speakers.

What exactly Am is isn't entirely known, though it is speculated that she's a consequence of the organic nature of Stemspace - it is believed that Am is an amalgamation of the inhabitants of the simulation, much like how Stemspace reflects the subconsciousness of the remnants. However, some believe that she might even be an organically grown true Artificial intelligence, having gone beyond the stage of being a shadow of the remnants' subconsciousness and achieved sentience and self-consciousness.
