Most of these are fallen watchers or "Watchers in the Dark"
Note that there is no pattern or reasoning behind GW's choices for their
characters' names. If you want more information on these
angels' duties and functions I recommend the above book, the Bible,
or Milton's Paradise Lost.
The next names are 103 fallen angels compiled from Enoch and others.
Alternate spellings are given. Note that since most of
these are translated from Hebrew, any alternate spelling is credible,
so change them if you want.
