Magic in Seven: The Days Long Gone is covered on this page. Very little is known about Magic in Seven presently, but the Devs have stated that it will be in the game and you will be able to cast spells.
Magic exists in the world of Seven, and while there's no room for logical explanations of some of its phenomena, it's definitely something you'll have to deal with. But although it's a common feature of everyday life, the way people access it and react to it can vary. Of course, simple farmers and labourers understand it differently than academics and scholars, but it must be said that the mage's path is not for everyone.
