Hear me out…jingheng but add some LanLong angst…Long was the first one to undergo the rebirth cycle and does so every few millennia. However, if their egg is disturbed/destroyed, they rebirth as a Vidyadhara.
For centuries now, Long has been rebirthing into Imbibitor Lunae. Because of Yaoshi's appearance, Long's egg has never be undisturbed, so they've never been able to rebirth into their Aeon form. Lan mourns this, mourns never being able to see Long again.
Jing Yuan, who Lan has long since shared a mind with, falls for Dan Feng, against Lan's wishes. They know the pain that Jing Yuan will go through, the pain of having to watch over and over their loved one rebirth.
But just like them, Jing Yuan is willing to endure.
Meanwhile, Dan Heng doesn't understand his dreams, doesn't understand what this painful yearning he is feeling, because the man in his dreams never has a clear face. He doesn't understand what all the cracked eggs mean, why the sound of a dragon crying haunts his sleep.
