Prohibited arts

The prohibited arts or dark arts, also known as the forbidden or elder schools of magic, are all the magic types whose usage is considered wrong in some way. Throughout the ages, the main regulatory agency of magic has varied, with the current one being the Magisterium. All prohibited arts aren't equally regarded, some are merely frowned upon, such as spirit magic, whereas some are legally outlawed and incur the most severe of penalties, such as blood and death magic.
The dark arts are opposed to the classical schools of magic.
