Fanghur resembled giant serpents around twenty feet in length, with leathery wings similar to those of dragons, but smaller, could not breathe fire, as well as were less intelligent than dragons. They had dappled green or brown scales. They stunned their prey with an immobilizing mental screech and then killed them. They usually hunted in groups of three or four. Dragons and Fanghur are distant cousins, but are less closely related than Dragons and Nïdhwal.
