Here's why:
* Magical properties: The peacock feather is a fictional element in the Harry Potter universe. It's described as a core material for wands, but there's no real-world equivalent.
* Real-world wands: Wands in the Harry Potter series are purely fictional. There are no wands in real life, and therefore no peacock feathers are used in them.
* Mythology: While peacocks have been associated with various cultures and beliefs, they don't hold any specific magical significance in the real world.
So, while you can't get peacock feathers for a Harry Potter wand, you can enjoy them as a magical element in the books and movies!
