How exactly does Glamour work? I know it is a magical spell that give Fables who aren't already human the ability to look like one. But how exactly does it work?
Can Fables really just swap between human and animal/creature form under the spell at will?
Does it require more Glamour to change back?
Are all Fables able to do this?
How long do these spells last if they require more of it? (Such as the case with Mr Toad)
For example Bigby seems to be able to morph between the human and wolf when angered or at his own will power. Without showing any signs of needing any extra Glamour. Is it just a special ability or can they all do something similar?
Forgive me if this has already been covered elsewhere, it's just something I've been curious about and wondered if anyone else had a solid answer or theory about it.
