Part of the fun for me in "soft" fantasy is figuring out what the rules are: oh, everyone is a dragon and in Victorian England only with cannibalism? you can walk through mirrors? your only vulnerable point is the ankle where your mom neglected to dip you in handwavium? Okay then! Just don't try to explain things to spoil the fun for me, or overplay my patience with too many giant, convenient "Actually, I'm not left-handed!" reveals.
