Mirabel's the owner and shopkeeper of Mirabel’s Magic.
The transformed the bookshop into a bookshop/magic shop clearing out most of the books and expanding the inventory with magical trinkets and potions.
She's not the best at managing her shop, but its location seems to make up for it.
She makes the charms, potions and elixirs mostly herself, though she has a section of imported goods.
She's a dreamer, friendly with the customers, but can let her thoughts wander off midway a conversation.
