Magic
When I originally settled on the title "magister" after http://orrery.prismaticmedia.com/2017/02/25/%cf%84%ce%ad%cf%87%ce%bd%ce%b7/, I chose it because I thought it a better alternative than "master," and "mistress" had kink contexts I didn't want to overload.
Tonight, reading old magical notes, I found Frater Pyramidatus' Glossary of Thelema. "Magister: The lowest Grade in the S⸫ S⸫ of A⸫ A.⸫ ... To attain this Grade one must swear the Oath of the Abyss."
Synchronicity is the universe's way of telling you to shut up and pay attention.
