The definition of magic itself varies between worlds, so I know it can get confusing. Magic itself might be thought of as a broad term for explaining... what I suppose would seem inexplicable to others who aren't able to utilize it for themselves. So you'll find a lot of differences in any circumstance where it comes up. So differences in where it comes from, how it's utilized, what it can be used for... even in one to one comparisons you'll find them.

Is there something specific that you wanted to compare? Certain abilities, or what might seem like limitations?
