Would shape-changing be dark or light magic? Say, to turn yourself into a bird or something.

Great question! I would say that, technically, it falls under Dark Magic. Simply due to the fact that the Mage is altering their appearance.

However, provided the Mage is not drawing upon an external energy source such as the Earth, it would fall into fairly neutral magic. Especially if the end result isn’t malicious! 

Perhaps a Mage has a totem or an enchanted jewel that they tap in to for shape-shifting?
