Aziraphale

Aziraphale is an angel and one of the main characters in Good Omens. He is a friend of Crowley's.

In the early days of Earth, Aziraphale was the angel set to guard the way into the Garden of Eden. However, after losing his sword and befriending Crowley (at the time known as Crawley), he is recalled back into heaven.

Aziraphale owns a second-hand bookstore in Soho, London. However, he avoids selling books whenever possible, as he is, in actuality, merely a collector of very expensive, very rare books, often versions of Bibles, such as the "Buggre Alle This" Bible and the Adultery Bible, among others.
