No, pretty sure it's the gnome game on Pottermore. :P Go explore it! Worst case, just make a new account now that it's open. Otherwise I guess you could work to sabotage Slytherin if you don't like it? XD Just start a bunch of duels and lose them on purpose or melt your cauldrons repeatedly! Mwahahaha!
I'm kind of torn, guys. ;~; The Japanese e-books finally went up on the Pottermore store and I really, REALLY wanna get them to help me practise my reading but they don't work on Kindle waaah. I hate reading things on my PC or smartphone but... but... Harry Potter books! Think it's worth it? :c (Especially since just importing the last books [they split all of the later books into two!] is like $50 per book before massive shipping costs because the books weigh a ton. ;__;)
