Palmyria : Huge list of angels; fallen angels; and demons
Sarah's Angels: Comprehensive source of angels and their roles
Umm... angel page thingy: Good list of angels.
godchecker.com: Because J thinks it's funny
Demonolgy: Names of demons/fallen angels (mostly)
with links that cite the origins/references to that demon. Nice little collection of information about individual demons/fallen angels. Good for fammiliarizing
yourself with the background for a citizen of hell.
List of Demons from Answers.com : A good
list of various demons/fallen angels from Mythology and various religions. Keep in mind with any of the demon lists, that some of the more 'fantasical'
aspects of them won't be able to be used in this story. I don't care if the description says 'fire breathing bird' your character will not be a
fire breathing bird. Rule of thumb at Sygil is nothing is to be too fantasy based, modify anything over the top to fit into the realism of the world.
The Jewish Encyclopedia: Angelology: If you have time to
read through it, it's a great genera; info site for the Jewish point of view on angelology. Even though we don't stick to a very strict outline of
angelology, I do try to incorperate a bit of everything in the story.
The Book of Enoch: One of the best apochryphal books for angelology.
The Book of Adam and Eve: Another apochryphal book, not so much on angels, but a
good one for the Genesis story.
The book of Ceremonial Magic: Arthur Edward Waite's book on angel magic. It's a bit... odd (Waite was a bit odd) but it's something to keep in mind when we want to do a 'by the book' innvocation.
The Magus: Goes along with the Book of Ceremonial Magic...
The Greater Key of Soloman: Same... magic.. angels... stuff...
The Grimoire of Armadel: Yet another 'magic' book. I'm
including these all for reference... :)
Fallen angels stories: Rather unbiased
look at fallen angels
