Diagon Alley

Did you notice?

A brick wall opens onto an economy: a bank run by goblins, a wand that has opinions, a list of school supplies treated as a quest. A pale boy in a robe shop offers a friendship that is really a sorting. Vaults and an empty one do quiet class commentary beside the wonder.

Foreshadowing

The wand’s twin core is a late-book problem about who else’s wand shared a feather. Gringotts’ idea of ownership becomes an argument, not a field trip. Both are planted here as shopping.

This echo points at book 7. It is a reading note, not a quote.
