Vast simulated environments and virchworlds where the inhabitants do not know their reality is an emulation, and may be poorly treated.
In most known virch worlds, all the properties of the world can be controlled by its people if they so desire. However, there is a growing opinion that most virches, and the most intensive ones, are not the known ones. Instead, many across Terragen space have concluded that at least some archai have vast simulated environments, simulated universes even, which they use to simulate possible futures, modelling worlds and universes using physics which accurately represents the physical world, and at as high a level of detail as is required for the task at hand (these would tend to be worlds where the minds of the inhabitants run directly on the simulated laws of nature in the virch). The entities in these virches, usually mobys who were 'born' inside the simulation, are not aware that their world is a virch, and nor can they control it, beyond whatever their role in the virch allows.
Instead, the virch is controlled by the archai who is running this particular emulation of reality. However, as the inhabitants do not know this, they are not in a position to protest against their treatment. These hypothetical worlds have become known as Bottleworlds.
Many people, and higher toposophic entities, are of the opinion that such virches are unethical, to say the very least. However, none of the archai alleged to be involved in such behaviour allow baselines, or indeed anyone, to inspect their thought processes, so it is rather hard to tell how true the allegations are. Despite this, some of the Archai who are alleged to be running these non-ethical virches are rather vilified for it, and several sophonts rights organizations are working to ensure that the Archai do not abuse lesser intellects for whatever reason, either in virches or in the physical world.
Some people suspect that, despite this, there may be at least as many entities in these unethical 'simulation' virches as there are in the known 'free' virches of Terragen space...
Microcosm (physical) - Text by M. Alan Kazlev A cosmos in miniature. Any self-contained world or universe. It may be real or virtual. Many sophonts and powers enjoy creating microcosms.
Virchspace - Text by M. Alan Kazlev Any digital space or environment; pertaining to virch or a cybercosm.
Virchuniverse - Text by M. Alan Kazlev Generally, an aggregation or collection of thousands of interconnected virchworlds or cybercosms, all sharing the same basic ontology and lay-out, to make traveling from one to the other easier. Sometimes also used to designate a single extremely large virchworld.
Virchworld - Text by M. Alan Kazlev A virtual world; usually at least partially self-contained, or apparently so, may or may not include sentient beings; generally part of a cultural community across computer/cyberspace/matrix networks. The Known Net consists of literally trillions of interconnected virchworlds.
