From my experience, that's normally the domain of demonic magic. We call it the Fel...and it poisons everything it touches. My father fell in battle defending our world from such evil.

But there is magic in the world back home that has no such foul origin. Shamans who speak to the elements of the world. Druids who commune with nature and its spirits.

...and priests, like me, who commune with the Light. Healing magic, as you say.
