This is the first public release of the Dragon-Book. It incorporates refinements to the text made by the author in 1998, 2000, 2001, and 2003, as well as corrections and marginalia from his own personal working copy and never-before-seen illustrations. This substantial work expounds the sorcerous ethos and praxes of the Crooked Path ritual system. Its contents include a cycle of ten extensive Mystery-rites, each accompanied by adjunctive solitary rituals and detailed commentaries. Additional texts relate the intricacies of Sabbatic ritualization, as well as an extensive body of stellar lore and ritual. The Sorcerous Formulae of Number and Sign are also communicated, together with detailed exegeses of the Quadriga, the specific covine-type of the Crooked Path. A detailed section on the Magical Weapons of the Draconian Sorcerer complements the text.
