Today i'm thinking about Decarabian being a primordial one parallel (he loves his people but is oppressing them and keeping them in a cage).
Venti fought for freedom and in the end he found himself and his people trapped in a bigger, even stronger cage.
And not just that, he is now one of the seven upholders of said cage, which only someone whose will can rival the world itself can break. So there's nothing he can do about it, except waiting for a star to descend.
Then, he would sing to the skies above, to the stubborn stone, to the surging seas, and to the stars beyond.
For he knew that someone must heal the hurts of the world, and thus someone needed to find a way to communicate with them.
"I was thinking that if I could move the stars to tears one day, I think I'd summon a meteor shower! ...Ah. Right. See this? This wind glider was the stars' answer. It fell from the sky, just like you!"
