Magic

Overview
Magic is defined as "the alteration of matter or the rules of reality via the usage of 'Ija' (idʒə)," or more commonly referred to as "mana." Ija is the smallest unit of material in the universe and can be manipulated to create anything. It can also be used as an energy source, and it can bend the laws of physics.

The Great Curve of Experience
While it is unclear where the curve begins and ends, all magic users go through a process known as The Great Curve of Experience, or The Curve for short. The Curve is a side effect to learning magic that gives the magic of medium skill users more stability but weaker output. It can and often frustrates mages to the point of giving magic up. The few who manage to pass the curve become some of the most powerful mages in the world.
