This is a classic mechanism. Evil folk are generally ugly (or with some kind of hideousness) while good folk are glorious, pretty, and by their white garb will you recognise the state of their souls.
This works well in High Fantasy (the Lore series is epic, not High Fantasy), but it’s also true it is somewhat overdone.
It takes all kinds to make up a great tale (as it takes all kinds in life itself, and we all know we should never judge a book by its cover, right?). Good and evil is in the hearts and souls of the characters, not in their features. A pretty face may hide malicious intent. That wart-ridden nose may hide a pure heart.
Prepare thus to be surprised by who is what in LORE!
