Because I’m wary of unleashing forces I know I’m not in control of and where I suspect those forces could turn on me and control yours truly! Also I have had it drummed into me by the Queen and Mother the Kingdom’s existence must not be exposed to humanity. I figure the less I use magic the risk of accidental exposure is reduced. I do use some magic to make life easier for myself but limit its uses as I don’t want Edward going through life thinking the answer to all his problems is to blast them away with a wand or a spell. And I would point out your own Queen doesn’t think all problems should be solved that way either. It tends to lead to being overthrown!
Paul has come to terms with what you are, mainly thanks to blaming your mother. Yet your mother married for love and gave up a luxurious life for it. What would you give up for Paul?
Mother also decided to please herself, Roherum. She could have made a decent match with someone of her ilk in your world. She was expected to do so. There is a very strong argument Mother did let your world down. She has also unwittingly put my Dad and I at risk and now Edward too. Mother admits there are nasty creatures out there drawn to those with magical blood. I’m not thrilled at that. As for Paul, yes I’d defend him to the death, magically if necessary. Though also certainly magic would be the cause of my having to defend him to the death in the first place!
