Targon and Nirvana?

So just my take on the new Aatrox interactions with champions like Kayle, Morgana, etc. The actual Targonian's as in the citizens of the shining celestial city atop the mountain seem to have the ability to move up or down the ascension totem pole, I mentioned Nirvana because I'm thinking it works something like this. You have your true gods such as Anivia, Ornn, Bard, Nagakabourous who can manifest physically if they choose and your Targonians who have an almost Marvel Asgard vibe of. "godhood" with the ability to temporarily possess a host in order to interact with the lower word aka Runeterra. The issue with Kayle and Morgana seems to be that one wished to become less inhibited by flesh (Moving towards Nirvana and Godhood) while the other might have taken a vessel and bound herself to being flesh lowering herself on the cosmic totem. Perhaps for power, perhaps for freedom from a people that would imprison their own inside weapons? Just a theory but let me know what you all think!!!
