Grigori jinni with a human women.
The Grigori or Watchers (Aramaic, עִיר, iyr; Theodotian trans: ir; from the root of Heb. `er, "awake, watchful"; Gk. ἐγρήγοροι, trans: egrḗgoroi; Slav transliteration, Grigori, "Watchers", "those who are awake"; Chaldean, "guard", "watcher") are a collection of jinn who were once in servitude to God. These were the jinn who banded together, swore a collective oath, and under the direction of Samyaza went directly against God's will by choosing to marry human women and father a race of children known as the Mugharribun, who by nature were destructive and murderous. The Grigori went on to teach humans the secrets of Heaven, such as astrology, cosmotology, gemology, and weaponsmithing. For these sins they were expiled from Heaven, hunted down, and punished. Most sources say that there are two hundred Grigori but typically only name the leaders, the Chief of Tens. They are described as looking like large humans who never slept and usually remained silent.
