Thestral

This black, skeletal winged horse is a unique breed that cannot be seen by all. Fittingly, it happens to be one of the rarest Patronuses in the wizarding world. Intelligent and loyal, this Patronus proves you shouldn’t judge a book by its cover.

“The Patronus is a kind of positive force, a projection of the very things that the Dementor feeds upon - hope, happiness, the desire to survive – but it cannot feel despair, as real humans can, so the Dementors can’t hurt it.”
