Alan Moore wrote Fossil Angels a few years back, and it was slated to run in issue #15 of the British occult magazine Kaos, but it never did: The magazine was sporadic at best, and issue #14, which also contains some Alan Moore writing and is available for free download here, was the last.

Moore recently gave Pádraig Ó Méalóid permission to publish Fossil Angels on his LiveJournal, Glycon. He explains:

I was lucky enough to be given a number of Alan Moore’s scripts by Alan himself a few years ago, and this was amongst them. I asked if I could publish it and, when another publication which it was slated to appear in folded, Alan told me I was free to go ahead. So, I am very proud to be allowed to present this piece on Glycon for its first publication anywhere.
