Liber Nephilim: A Grimoire of Fallen Angels by Frater Barrabbas

Frater Barrabbas presents a guidebook and grimoire for working with the Nephilim, described in tradition as the first angels to fall, who taught ancient humanity the ways of civilization.

He sets out a new grimoire for spirits he notes were omitted from medieval magical lore, as a starting place for engaging them as magicians of ancient times once did.
