Omni-Galaxy

The Omni-Galaxy contains 100 billion Omni-Surfaces and multiple races of Omni-Aliens.

Types of life
There are multiple types of life in the Omni-Galaxy, such as Omni-Humans, and other races of Omni-Aliens like the Omni-Knuberis and the Omni-Larjins. However, there are also Omni-Stars, which actually have life and can breathe and speak. The Omni-Stars Are the main reason of heat in our local Omni-Surface.

Multiple Omni-Abstracts?
Yes, there are multiple Omni-Aliens That each represent all abstract things. The way this is possible is because of alternate versions and definitions of "abstract". For example, time might not be abstract in another Omni-Alien's home Omni-Surface.

The Omni-Blackhole
The Omni-Blackhole is like the blackhole in the middle of normal galaxies, but in this case it's depicted as a destroyer of concepts and ideas. It's arguably one of the biggest threats in the Omni-Universe.
