The Book of Tagirion. The Draconian Grimoire of the Black Sun

This book presents two works on demonology.

The first work is the grimoire of Asenat Mason. It includes rituals and meditations through which practitioners can pass through the mysteries of the Black Sun. You will also find the invocations of Sorat, Belphegor, meditations on the Black Sun, and rituals of the Opponent.

Sigillum Diaboli by Stephanie Connolly is a comprehensive guide to divination using demonic sigils. This work contains information on how to create sigils, how to conduct divination sessions, and also includes the meanings of over 85 demonic sigils.
