This book does not dare claim that this will cover all of them, but it does dare to cover the broad strokes on a certain subtopic of the lives of those touched by the Supernal who still reside in the Fallen World: their toolkit.\n\n<b>Mage: the Awakening</b> covered the broadest strokes on Awakened life in general, but there is so much more to the means by which Mages conduct their affairs and pursue their Obsessions that simply is not covered in that volume.

This line of thought naturally extends to all of the Conditions, optional Arcana principles, alternative Relinquishment methods, and so on.\n\nThis book was written on a rolling basis by a number of people. It is a compilation, that accumulated over time. It did not get created overnight. As such, by the time you receive this file, there is a good likelihood that it's still in development, which means there might be more up-to-date versions of it, and additionally it may be open to input for your spells, your Artifacts, and your optional rules.

It is a grimoire of grimoires, much like the book that White Wolf released when they still called themselves that, and is a combined set of spells that the players of this community have mutually agreed are at least somewhat reasonable.
