The Watchers

The Watchers (also known as Grigori) were a group of Fallen Angels who mated with humans to create the race of hybrids known as the Nephilim - 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 knowledge humanity 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.
