Since Aurelion Sol can create and destroy stars...

Sounds like she is fucked.

celestial beings aren't exactly corporeal and influence the realm from a different dimension

they're interdimensional

the aurelion sol teaser implies he's corporeal and in the dimension, just in space

it might actually keep him, lore wise, a notch of power down from beings like bard and pre fall soraka

that is if he is just a dragon, and not a celestial being himself

"The stars cry for you... Lie! I can't even remember your name." I think this is directed at Soraka as she used to hear the stars, until she used violence...
