Finished in 1202, Magus Sententia is a tome written by Draco Nigerius of Bjornaer. Written in several volumes, the work took him many years to complete. The first several volumes serve as a primer on Magic Theory while the latter ones introduce more advanced concepts. Like many of the works by Draco, the book was not found until after he had entered final twilight. The original tome is scribed with a Quill of Unsurpassed Quality, so any copies not copied with a similar item will be at -1 quality.
