All magic is suddenly gone. No mage can sling sorcery anymore. This upsets all empires and civilizations. It is soon discovered though, trough the combined work of mystics, scholars and dreams, that all the magic has been drawn into a single orb in a vast tower located at one of the poles. Whoever gets there first wins the greatest price in history, access to all the magic in the world. But who owns the tower?
The more you dominate your life to a god or goddess, the more you gain magical powers from him or her, but the big stuff does not come easily. Most worshippers have only the weakest of spells.
