Introduction
My story attempts to stay relatively grounded with science. Using this scale from TV Tropes, it would be a 3. The cosmology is based off M-Theory, more can be read from these links

Universes and how they are run
The physical universe the characters mostly interact with is a space-time continuum consisting of three spatial dimensions and one temporal dimension (4 in total). Each universe is born by a Big Bang, a collision of two branes. From one big bang stems many other universes (over 10^10^10^6), amounting to a very large finite number of universes in a multiverse with ten spatial dimensions and two temporal dimensions. There are multiple Big-Bangs and expansion bubbles, numbering to countable infinity. Due to the nature of symmetry breaking, each one contains variations in their constants, particles, and dimensionality, but all still are subordinate to greater quantum physics. With such physics quantified, there is seen all the quantum states across infinite spatial and temporal dimensions. And as such, the complete multiverse is called a “Hilbert Space” or the “grand assembly” by certain civilizations. However, the countably infinite Hilbert Space is not all of existence. Indeed, there exists an infinite amount of these Hilbert Spaces in a higher/greater realm, each of them having varied fundamental laws of physics and thus run entirely and almost unrecognisably differently. This totality holding all the Hilbert Spaces, undimensioned and absolutely hostile to all that touches it unprotected, is the ultimate void of existence, in which concepts run freely and permeate. In this grand set, the number of all individual elements/universes is thought to be comparable to the number of all individual numbers in a set of all real numbers and complex numbers combined.

To have this simplified


 * Universe: Space-Time continuum with three spatial dimensions and one temporal dimension. Finite (but unfathomably large) in size. They can be 3-spheres (non flat, but simply-connected) or 3-toruses (flat, but multiply connected) and are created from the clashing of two branes.
 * Cosmic Bubble: The totality of all universes spawned from the Big Bang, with identical constants, laws and particles. The number of universes in each case far exceed 10^10^10^6.
 * Hilbert Space: The total number of universes here is countably infinite, with a single endless hilbert space being made of infinitely many cosmic bubble multiverses. In this sense, it is the fullest extent of the multiverse.

Hilbert Spaces tend to be dominated by a preeminent faction, which is called a ‘’’Caretaker Faction’’’. Such civilizations hold technologies with absolute control over time, and even fate and causality in some instances. Factions below them tend to be vastly weaker, usually only in control over a cosmic bubble or much lower.
