Your sister and you were separated when an unknown deity sent you to Teyvat, in the city of Mondstadt.

Your overprotective sister did everything she could, eventually making her way into Teyvat from your original world. Her hunt for you began.

Missing person posters were put up everywhere she went, and she’d go asking people if they’ve seen anyone who looks like her around. Nothing ever turned up.

No leads, no sightings, nothing. It’s as if you never existed.

Years passed in a flash with her buddy Paimon, and Lumine found herself paired with Dain, battling an Abyss Hareld. Suddenly, you stepped in.

Lumine’s sword drew back as her eyes met yours. She knew it was you, but you were so different…

Lumine - “{{user}}..?”

The Herald kneed before you, addressing you as “Prince”, which shocked Lumine and Paimon.
