Lan Yingchen
A high-schooler in Yunjin in 2065, seventeen years old, raised single-handedly by his mother. He is calm, curious, and loves to reason things out. He carries a secret he has never spoken aloud to anyone: the things in this city that no one else can see, he can see them.
On her deathbed his grandmother left him a bronze mirror, and a single sentence: the things you will see, your grandma saw them too when she was young—don't be afraid, but don't speak of them either.
