Shahbaz (Persian)
Shahbaz is the name of a fabled bird in Persian mythology. It is described as having a body similar to an eagle, being bigger in size than a hawk or falcon, and having inhabited an area within the Zagros, the Alborz, and the Caucasus within Greater Iran. In ancient Persian mythology, the Shahbaz was a god who helped the Iranian peoples and guided the Faravahar to the Iranian lands.
Many Magizoologists speculate Shahbaz to be related to Firebirds, especially given their proximity to the known extended range of Arabian Phoenixes. Generally impossible to catch, there is one recorded occasion on which a Shahbaz interacted with humans willingly, leading them to safety.
