I'm not sure how to summarize this, without it sounding absolutely crazy. I'll make an attempt though.
Long before humanity was even an idea, there was a species of deities, known as the Primaries(I'm not sure of the name). Almaumations from the birth of our planet with the ability to shape it how they wish. They formed geological features to start. Until the Primaries got bored, and started shaping animals, then finally humans. And the humans worshipped them, gave them offerings, sacrifices, and praise. The Primaries enjoyed the worship, but even they couldn't live forever. They were buried in shrines, where their presence was easier to ignore, thus, leading to less and less worshippers. Each time they lost one, the more hurt they became, until it came to a head and they took out their anger on their favored creation.
(The first chapter will be the display of their anger.)
After what was dubbed "The Cataclysm" some children were born with unique traits and abilities. Some believe these abilities are a gift from the Primaries, to get humanity to favor them again, some belief it's a way to remind humans of their existence.
Theres more that I could add here and probably should, but meh, if I feel the need later I will.
Oh also, this is mostly by me, but I will be drawing ideas and inspiration from other things
