It's pretty obvious people look inside this book since wondering Muggle minds are so curious ... curiosity killed the cat you know ... it may be a private society ... but this book is also public ... so this society is known to just a few Muggles right now ... so you can give it up ... I don't care ... just you can't become a member of the society because you don't have a card ... the card means I chose you ...

Not to be rude or anything ... maybe this society will spread ... who knows ... being known to all Muggles ... no matter ... just stay away from us ... because I don't want my precious and dearest subjects hurt ... we're peaceful creatures despises legends and pasts ...

Obscurus are actually mostly known their personality to be quite innocent and loving ... they're just really terrified because of people like you ... Muggles ...

Again ... no offense ...
