As has been implied before, angels — though filled with God’s divine grace — are eminently corruptible in the corporeal world (physical plane) and, perhaps more importantly, when in the presence of humans. The Grigori, designed as the type of angels farthest from divine, proved to be so much more corruptible that it wasn’t long before their enormous zest for physical life, proved to be their undoing, from a spirititual perspective.
They took husbands and wives among the humans and led greatly debauched lives, neglecting their heavenly duties.
Legends tell us that the children the Grigori begot were hideous, misshapen monsters, now known in demonic circles as the Nephalim, and that a group of angels were quickly dispatched to destroy the half-breeds, after which the Grigori were damned to Earth for the remainder of their long lives.
This is mostly true. The Grigori, both for the sin of lust and for neglecting their duties, were banned from Heavenly society, doomed to spend the remainder of their days roaming the Earth.
The Seraphim Council believes that even speaking the name of the Grigori disturbs the Symphony — they refer to them as the Watchers, since that was their original duty. What few angels know, even today, is that besides their more famous gigantic spawn, the malevolent Nephalim, the Grigori did successfully engender half-breed children, part-angel and part-human.
