[quote=Windreda] The actual origins and how it is used is a mystery, but less out of laziness and more of having your ignorance flow into the characters (Shh just let it flow over you).

Haha dis line

In all seriousness though, I don't think magic ever needs explaining beyond "This circle conjures fire!" or "This incantation conjures lightning!" you kinda start to lose the charm if you try to actually explain how a singular spell does it's thing(unless you're type moon but nobody writes like type moon)
