Grimore - Book Of Change

Knowledge is power, and thus power comes from books. Grimoires contain the magic you need to survive in the world, especially against beings of complete and absolute power. Ver and Devi and twins that should never have been born. And they were despised for it. They've never known anything but the phrase 'Kill or be killed' and dying was something that they didn't fancy. They set off on a journey to gain power. Power to change everything. But at at what cause?
