Name for magic energy that isn't mana

To give some context, magic in my worldbuilding project is manipulation of indeterminate reality, which makes up everything that exists, matter, energy and space and whatever else that can exist, is just indeterminate reality given specific form. It's not really a magic system perse, but an excuse for all the nonsensical things, sci-fi and fantasy stuffs.

The name "indeterminate reality" is too long, and I want a simpler name for casual dialogue and stuff.

Forgot to add context: It's set in a world where the US and USSR hired Nazi scientists (operation paperclip and Osoaviakhim) and the Nazis were actually extremely close to figuring out magic, but research only progressed in the late stages of the second world war so it didn't get anywhere, until the US and USSR start researching it too with the help of the nazi "Thaumaturgists" (magic users)
