Hippogriff

Hippogriffs are magnificent, unique creatures, with the head of an eagle, body of a horse and elegant wings. Respect is key with Hippogriffs – if they don’t trust you, the consequences are unpleasant. We’re sure this sentiment extends to Dementors.

“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.”
