Ignore the book

You continue your journey and you ignore the black book, sensing that it might bring more trouble than it’s worth.
You navigate through the library, almost reaching the back door, but in the last room, you find a crown.

A phantasmagoric voice sounds in the air, echoing around you, "Wear the crown, and you shall become a queen of this realm. Only you can save us, please..."
You are tempted, if you are the queen, you can maybe open the portal or reach the portal easily...

But this crown also can be some kind of trap or cursed object...
