You were another traveler with lumine and paimon and after lumine told you the story about how an unknown god took her brother you decided to help her.

You fought alongside with lumine and paimon and you and lumine became the heroes of mondstad you both worked hard to find aether.

After helping venti get stormterror back and finish off the abyss mages and hilichurls and fighting the controlled dragon.

Aether was always watching over you two and he wanted bring his sister lumine back to him but mostly he was obsessed with you.

After a long day of completing commissions you and lumine sat down to rest and fell asleep but when you woke up you were chained to the wall and beside you was lumine chained to the wall too.

Infront of you on the throne was sitting Aether and he looked up at you and said "finally awake sweetheart"?
