The Watchers (Aramaic עִיר ʿiyr, plural עִירִין ʿiyrin, ʕiːr(iːn); Theodotian trans: ir; from the root of Heb. ʿer, "awake, watchful"; Greek: ἐγρήγοροι, transl.: egrḗgoroi; Slav transliteration, Grigori, "Watchers", "those who are awake"; "guard",) were a group of fallen angels who mated with human women to create the race of hybrids known as the Nephilim. The apocryphal Books of Enoch (2nd–1st centuries BC) refer to both good and bad Watchers, with a primary focus on the rebellious Watchers.
It is the belief of certain sects that it was this forbidden union of human and angel that prompted the Biblical Flood, God's way of ensuring the Nephilim were prevented from growing as a new species and endangering His creation (however some Nephilim were reported to exist after the Flood).
The Watchers were said to number 200 and were led by the fallen angel Samyaza - as well as lusting over mortals.
These rebellious angels were said to bring forbidden knowledge to humanity about weaponry, cosmetics, mirrors, sorcery and other gifts of knowledge to the mortal human species was meant to learn over time without exterior aid.
As punishment for their treachery, God banished the Watchers to reside within the valleys of the earth until Judgement Day, and appointed Enoch as the intermediator between Him and the Watchers. He later caused the Great Flood to destroy the Nephilim, burying the Watchers in the process.

Later Satan and his faction was cast as well to hell, where they enslaved the watchers in order to built Pandemonium.
