The cosmic entities are a group of humanoid beings who possess vast cosmic power that they tend to
use in strange, idiosyncratic ways. No one (except, presumably, the Galaxars themselves, and perhaps other beings more powerful still) knows what relation the Galaxars bear to one another. Each is a distinct individual with his own powerful personality and notable quirks. They don’t seem to have come from the
same species (though there’s no way to know for sure), and don’t necessarily even get along with one another very well. Some theories that have been proposed for their origin include:
* each of them is the recipient of the “gestalt energy” of entire extinct species, and somehow embodies one of the key aspects or traits of that species.
* they are the surviving members of a star-ship crew from an ultra-advanced pre-Big Bang civilization that somehow survived the Collapse/Bang and emerged from the experience with vast cosmic power
* they are from the first group of species to evolve in the Milky Way over ten billion years ago; each of them is, in effect, a “mutant” member of his own species powerful enough to survive for billions of years
* they are living “manifestations” of philosophical concepts, innate sentient tendencies, and the like
