Lily: For us, the magic isn’t good or bad, it’s just that stuff like shadow magic is more useful when you want to do bad things.
I will note that darkness for my world connotates something different. Shadows and physical aren't always bad, they're just associated to bad things. However, darkness in the metaphysical sense is bad, negative emotions, negative intentions, fear. I believe we had this philosophical discussion of whether I'd like to live forever, death is associated with darkness as it is the opposite of life which often associated to the light. Death isn't necessarily a bad thing, it marks an end to a storied life and a transition to new beginnings - that is if you believe in reincarnation. It is those that desire to bring death that is marked in darkness, true darkness. In the same principal, there are differences to physical light and metaphysical light. For that you could probably just flip everything I've said for darkness.

Anyways, I think you can see why I want to be a teacher.
