Jabor is a higher djinni who usually takes the appearance of a tall, red-skinned man with the head of a jackal. Jabor has been described as "moronically strong to the point of indestructible"; coincidentally, he is somewhat lacking in intelligence. Bartimaeus destroyed him by luring him into a rift caused by the arrival of Ramuthra - he was apparently torn apart. He preferably uses Detonations.
One of Jabor's former masters was Set. For a century or two Jabor was in a temple in Ombos (a city in Egypt loyal to Set) where he fed on the human sacrifices brought there, until the temple was destroyed by a Pharoh from lower Egypt. Jabor also worked in Phoenicia.
