Huh. Protection and Love are concepts that were created by Humanity (?), while Beginning and End are fundamental concepts that were created during the birth of the Universe.
While Rukia's reply to you is satisfactory in one way, I also like to point out that this is an
utter misconception for Crystalwatcher's universe.
Love and Protection are in no way the creation of humanity, not by a long shot.
Forget [ Time ], forget [Beginning], forget [End].
The only reason anything [Exists] at all is out of Cosmos' [Love] for Void. Out of that love she decided to instigate it all and force everything to exist.
Also Love is something specifically mentioned as a thing that Cosmos brought with her when she stepped into existence.
And there is a reason that both Cosmos' and Void have the "guardian of Cosmos" ability in reference to Void.
You could say that
Love is what Cosmos represents most outside of her affinities, and that Protection represents Void the most outside of her affinities.
Rather, those two qualities are in ways more central to them than most of their affinities are.
[Beginning] and [End] might have [Existed] before [Love] but if not for [Love], [Beginning] and [End] would never have existed in the first place.
Love and Protection are nothing to scoff at conceptually in this world, and are every bit as fundamental to it existence as [Beginning] and [End] is, if not more so
