The Origin Realms were mostly unpopulated, and there were two major reasons for that: the first was that each Origin Realm was incredibly vast, and an easy estimate of their size would be twenty-three times bigger than the biggest Reality in Existence.
Their true size could only be truly appreciated by Primordial-level beings, as size for lower-dimensional beings becomes meaningless after a certain point because, to their limited perception, it becomes infinite.
The second reason for this lack of people was that Eos had charged his Primordials to create superior beings worthy enough to inherit the power of each Origin Realms, and he had brought forth his creation, the Elythrii, as an example for all of them to follow.
