I'm trying to fine tune a concept in my fantasy story and it's pretty loose so bear with me.
So in this world I'm writing I have a few different systems of magic going on, most of them racially based. I wanted humans in this story to not have any inherent magical ability and be masters of industry and commerce instead in the world. However I wanted to have a type of small "holy order" with human paladin and witch types in the story, but instead of drawing their power from a patron deity they get it from within themselves powered by their will or "spirit". Like for the paladin types they would have soul-bound weapons that can burn away evil and the witch types taking on more of a support role with healing and defensive magic.
Essentially it would be a kind of magic that isn't insanely powerful, but it's not easily obtained either to balance it out.
Thoughts on how to better fine tune it?
