You take the Very important from out of the bookcase. You don't know when you'll need to conjure up some spell that you forgot when you were a kid, and you'll have the book right there with you. And yes, before you ask, this book has the very important page covered in quacks. It's a shame too, it's a really old book, and some of these spells have only just now been possible, but the page covered, and the page taken out were some wierd tecnical spell that slightly altered the density of a grain of sand several light years away.
This book is the aforementioned book that your father used to summon you into your Vessel, and he used one of the first spells in the book to do so, funily enough. This book was the one you advised the guy in yellow pajamas a few scrolls upwards to use in his mother's resurection. Its a shame too, you would've loved to talk to Meowrage's mom, but alas, you can't do that (at least to your knowledge).
You prepare to head inwards towards the circus tent, but first, the cat in yellow pajamas.
