Watcher Angels according to ThBook of Jubilees, are the sons of God sent from heaven to instruct the children of men; they fell after they descended to earth and cohabitated with the daughters of men — for which act they were condemned and became fallen angels. But not all Watcher angels descended; those that remain are the holy Watchers and they reside in the 5th Heaven. The evil Watchers dwell in the 3rd Heaven or in Hell.
The mysterious eighth order of angels, the gentle Grigori were created by God to be Earthly shepherds of the first humans.
The Grigori were both physically and spiritually gigantic, at least by the standards of the people who later wrote about them. They served early humanity as vast reservoirs of information concerning the finer points of civilization, and their selflessness was beyond compare.
They were also called the Watchers, as it was their job to observe humanity, lending a helping hand when necessary but not interfering in the course of human development.
