Within the Boundary Between Realities, those experienced could quickly distinguish between Emerging Realities and Prime Realities.
Emerging Realities were newly born as they had little history and power, with most of them more often than not having existences below the Cosmic Realm in power, and they were considered lands to be protected from the naturally rising Primordial Beasts within Realities as those who had forged Ascendancy Halos could even obtain an Authority as Overseers to protect these Realities and gain benefits of their own!
Then…there were Prime Realities.
Vast and shockingly old Realities where existences had settled into for many eons.
Powerful Bloodline Races resided in such Prime Realities as Higher Existences were abundant, with many Prime Realities falling in the hands of Primordials as their influence was undoubtedly the most far reaching!
