Bastardy/Opportunity - is that one of the stories you mentioned before? Not sure. Sounds really cool, though. I don't think I've ever read anything like it...
It’s giving me fits. Sadly, can't help you with that...

Sometimes, when reading the Harry Potter books, I got a bit annoyed with how 'undefined' the magic is. In the last book there was suddenly some really complicated stuff about wandlore, but magic itself was still quite a mystery. Now, I can't be anything but grateful that JKR left it so open to interpretation, and your imagination can run wild with it :D
Looks like some more amazing magic you've come up with in A Black Stone in a Glass Box. Wow.
