Who are the gods of League?

Nagakabouros is seemingly the only true god-like being within the League of Legends universe. There are other very powerful entities but does anyone know what the difference is between a being like Nagakabouros and something like the Aspect of Twilight? To my knowledge, the only beings that could be considered in the running are the Freljordian Demigods, the aspects found on Targon and their ascended warriors and, the God-warriors and ascended fighters of Shurima. The issue I see is that all of these entities are powerful but material, Aurelion Sol was captured by the Targonians, I feel like Godhood is something greater than that. The Solari and Lunari both worship the Sun/Moon but does that mean there is a Sun GOD and a Moon GOD or, since they both are on Targon, are they just worshipping the aspects of the Sun and the Moon.
Can someone clarify?
