Dimensions

Dimensions

The number of accessible (space), causal (time) and background (inacessible) dimensions. The universe as it’s known today has 3 accessible dimensions and 1 causal dimension.

Accessible (Space)

Adimensional Space: Punctual existence. Whatever exists in the realm -is- the realm, with none of that pesky distance business here.

Unidimensional and Bidimensional Space: Linerealms and Planerealms aren’t very popular, since they depend on very unusual physics to function properly and are quite cramped. Use of Bidimensional realms as wallpaper is hitting a new high, however.

Tridimensional Space: Height, width, breadth. North, south, east, west, up, down. Favored by most known realms, allows for relative spatial freedom without much complexity.

Tetradimensional Space And Further: Spaces with more than three dimensions get very complex and very large very quickly. Useful for compact storage and mind-bending mazes.

Causal (Time)

A custom notation is used for different time dimensions here. The standard ‘past’ and ‘future’ are called 1-past and 1-future, and the normal time dimension is called 1-time. Further time dimensions are called 2-time, 3-time, etc.

1-time – The progression between past and future.
2-time – Progression of timelines, from the original (2-past) to 2-future.
3-time – Progression of the timescape, from the original (3-past) to 3-future.
ω-time – The Substrata time dimension, it pins other realms’ timelines to itself. Can’t be traveled through in either way.

Adimensional Time: Timeless realms never change, from creation to destruction. They’re hard to enter, and impossible to leave. They’re very useful if you need to protect an item, place or person from the ravages of time, or indeed, from the ravages of anything. An adimensional time realm is the perfect prison.

Unidimensional Time: The timeline we’re used to. We move from the past, towards the future: The past is frozen and the future is not there.

Bidimensional Time: Time still proceeds normally, but with the appropriate means, one can step back and forth along the timeline and alter it. The timeline itself moves through 2-time: It has an immutable 2-past and uncertain 2-future, so that new changes overlap old ones, ad nauseam.

Tridimensional Time: Also known as Time Cube. As 2-D time, but former timelines remain acessible in the 2-time dimension, and altering them branches the timescape even further. The timescape grows in complexity through 3-time.

Tetradimensional Time: The states of the timescape itself, from the initial timeline to the ‘final’ one, whatever it is, are available for travel, and altering the timescape in 3-past branches it in 3-space. This is usually one dimension more than anyone in their right mind would ever need.

Background Dimensions

These dimensions are not normally accessible (unless someone is really willing to take a spanner to the dimensional works of the realm), but may be used by the realm’s geometry or timeline to reshape it into loops or tangles. (For example, Mondo has two background dimensions used purely for things such as corkscrew-shaped streets and connecting every toilet directly to the central septic tank.) More of a paperwork thing, really.

Layers

Realms that are unhappy with their current dimensional status but don’t want to go all the way to the next dimension can use layers to beef up their spacing. Layers are essentially discrete dimensions: they are to dimensions what natural numbers are to real numbers. You jump straight from one layer to another via a glowing gate or whatever, instead of 4-dimensionally walking there.
Realms can have any number of layers, from 1 to infinite, in as many dimensional axes as they wish. (A 1-layer realm is just the standard thing. A 0-layer realm is silly.)
