The Thaumonomicon is the book in which one records all of their knowledge of Thaumaturgy, and where one can find new topics to research. It will serve as the main reference point for almost anything magic in nature, from where to find such things to how to create them. Thaumonomicons can either be created by using a wand on a bookshelf, or found in a dungeon or stronghold chest. Obtaining a Thaumonomicon will often be an aspiring Thaumaturge's second step, only after creating a wand, as without a Thaumonomicon, it is impossible to refer to anything magical or to find new research options, so it is quite necessary for one to advance their knowledge of Thaumaturgy or for new Thaumaturges to create items magical in nature.
