Imperial Age Magick
From Victorian literature and actual occult practice to later fiction set in the era¸ depictions of magic (or magick¸ to use the spelling proffered by Aleister Crowley) are varied. 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¸ creating a system that is specifically and inherently Victorian in tone.
"Imperial Age Magick presents several magical styles for the Game Master to choose from when creating an Imperial Age: Magick campaign¸ whether that involves faerie court intrigues in London¸ the private wars of occult secret societies¸ or even Oxford Dons fighting eldritch horrors - all within the context of the familiar and accessible d20 Magic System. By combining the options offered in this supplement (all based on real-world Victorian occult practices)¸ a GM has a total of nine magick systems from which to choose¸ each scalable to suit the power level of the campaign.
"Including details on actual Victorian occult societies¸ New feats and skills¸ and the Hermetic Disciple advanced class¸ Imperial Age Magick is everything you need to add period-appropriate magick to your Victorian-era d20 campaign.
