This is meant as a supplementary after reading a considerable portion of my book.
If you have read through my book, you would have understood by now that my series contains various "power scaling" systems. One thing to immediately note is that I do not intend to mimic similar web novels. There won''t be ten or twenty Realms above Fundamental Realm. There won''t be complex divisions between Realms beyond what is mentioned. I intend to keep this simpler and cleaner. In fact, the only reason I introduce a "power scaling" system is to simplify the complex power disparities that will present itself much later in my series... This is my way of organizing the world in discreet forms.
Furthermore, I like to emphasize that Realms/Core Levels/etc are not truly indicative of an individual''s prowess. A toddler at the Perception Realm would easily be beaten by an a.d.u.l.t, even at the Fundamental Realm. It does not make them almighty! Defeating individuals with a "realm" difference is not impossible, assuming they are on equal level field (if that makes sense?), though it is incredibly rare. Here, realms means levels across any power system such as Fundamental -> Perception or Gaseous Fog -> Condensed Drop. What I mean to emphasize is the qualitative transformation from one realm to another. For example, Perception Realms have superior sensory capability and Condensed Drops have Magical Energy dozens, if not hundreds, of times more Gaseous Fog.
Finally, there will be five(?) planned power "systems" in total. These five will encompass nearly all, if not everything, that I can think of, both in the present and the future. For sake of simplicity, Volume 1 does not explore the other three systems. Instead, it focuses on the Realms of Mastery and the Core Levels. This is not to say that they do not currently exist in the world. They do, just unmentioned.
Realms of Mastery (Physical Body Mastery):
1. Fundamental Realm
2. Perception Realm
3. ??
Core Level (Magical Core Mastery):
1. Gaseous Fog
2. Condensed Drop
3. ??
