Perhaps I should've said "world" instead of "universe". You cannot deny the fact that humans are the predominant species on Earth.
That only explains the motives of The False Gods. What about the rest?
Elementals think and act just like humans in the real world. All of them want power, wealth (electrums), etc. Except maybe that the elementals do not have sexual desires like humans, because they're genderless in my story.
But that leads to another question... Do elementals have genders in your story? If not, do they reproduce asexually? Or do they not procreate at all? I'm highly unsure about this in my own story.
And what do elementals look like in your story? I've explained that in my story, elementals look like colorless and translucent humanoid beings made of energy; only their Marks in their cores are colored. But as they absorb quanta, they gain color. I don't think one type of elemental should only have one color; for example, a Fire elemental can absorb both Fire and Air quanta, and it would have an azure and red body and a red core.
