I've only skim-read the school pages so the stuff I already had down will probably need a factual edit at some point. It's the Polish character who'll need the most work, mostly because I know Anais so well already (and she's basically done anyway, game tweaks asides), and because I need to re-visit my WW2 knowledge and the stuff about Grindelwald from canon before deciding fully on his character history. Poland just seemed like a good bet because of the size of the Polish population in the UK, really!
(Oh, and if anyone's nosy - BB gal and Durmstrang boy. Apparently, I don't do things by halves when it comes to names and native languages ;) )
