From the introduction: The Imperial Age setting is designed to encompass a wide range of sub genres within a period setting. Some Game Masters will wish to incorporate the use of magic (or magick, to use the spelling proffered by Aleister Crowley) into their Imperial Age campaigns. The Imperial Age: Magick does not attempt to present a single magic system. Rather, it is meant as a tool kit for GMs to design the magick system that best suits their campaigns by mixing and matching numerous elements.
