I am working on a multiversal story, and Im currently on the planing and worldbuilding stages. It is inspired on the concept of "Planes" like in Magic the Gathering, or DnD, however, the story has more of a science fantasy style.

What I need is a word that could be used instead of "Universe" or "Dimension", like how the previously mentioned franchises refer to their interconected universes as "planes"

I can use made up words, coming from a conlang even if you wish. What I would enjoy is that the word had a Latin-esque inspiration or feeling to it.

I can also use alternative words in other languages as inspiration or even synonyms of universe, world, dimension or plane.

Take in mind that the word will be usted in several contexts, like for example traveling, similar to words such as interdimensional portal or extraplanar gate.

I hope this is an interesting exercise of creativity for you, and I really appreciate the effort and thought invested on this, I will try to reply and give my opinion on any suggestion with respect and an open mind. Thanks!

The word "cosmos" is from the Greek "kosmos", meaning "complex order". It is used 186 times in the new testament, and not in reference to the "heavens". It is used to refer to people outside christianity.

John. 18:36; the human race external to the Jewish nation, the heathen world

Rom. 11:12, 15; the world external to the Christian body

The Greek term for "everything" was τὸ πᾶν tò pân ("the all"), although that didn't include "the void".

The word "universe" means literally in Latin, "one turn". In the bible, "universe" is synonymous with "heavens". The word in the old testament for heavens is shamayim, which means the sky. To the ancient Hebrews, anything "up" was "sky", equaling "heavens".

The point of this is the word "cosmos" is being found to be factually incorrect, or mutually exclusive. It was a view that the "heavens" were complex, but they were also supremely uniform. We are directly observing how chaotic the "heavens" are, blowing up, colliding, throwing itself apart, anything but "cosmos" smooth order.

The word "universe" for the "heavens" is more descriptive. One Turn, one shot, YOLO. It is symantics but it affects our cognitive perceptions of the meaning of words applied to the physical phenomena. Cosmology, by virtue of the connotation of the word is about the study of a complicated but smooth "heavens". It would be more descriptive to call it shamayimam-ology, the study of the sky.

The reason this is important is how so many people get fixated on the word "universe". The word "universe" does not mean "the all" or "everything". It means one turn, one shot, one existence, one state of being. Books and titles with "cosmos" actually indicate they don't know what they are talking about.
