The four main magic using races had a different viewpoint when thinking of magic as a resource.
The Dwarves saw it like any other material, they mined it, so they could refine it and then store it for when they needed to use it.
The Elves saw it as part of nature, and strove to keep it balanced with all things, as it should be.
The Humans just took and took and took, never understanding why it would run out for them at times.
And as for the Orcs, they saw it differently.
Literally, their eyes could see that spectrum.
