🜍 Fraternitas Saturni (FS) – The Brotherhood of Saturn

The FS broke off from Aleister Crowley’s Ordo Templi Orientis (O.T.O.) after internal disagreements—especially around the role of Thelema and Crowley's authority.

Key features of the FS:

• Astro-magical system focused on the influence of Saturn as the central planetary force.

• Combined elements of Thelema, astrology, ceremonial magic, and Luciferian Gnosis.

• Emphasized individual spiritual development, self-initiation, and a personal connection to “Saturnian” forces, representing time, limitation, karma, and transformation.

• Strong influence from Crowley, but not entirely Thelemic. FS viewed Lucifer not as evil, but as the bringer of enlightenment—a Promethean figure.

📚 Gregorius’s Writings

Some of his most important books include:

• "Magische Briefe" (Magical Letters) – A collection of his core teachings, originally published as letters to students. Deeply practical.

• "Saturn-Gnosis" – The central doctrine of the FS, outlining their Saturnian worldview.

• "Der Weg zur Einweihung" (The Path to Initiation) – A magical training guide, often compared to Bardon’s system, but more theosophical and lodge-oriented.

Much of his work was written in coded or symbolic language, designed to be deciphered by initiates or serious students.
