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!
