(MC POV)
Luna brought both Rina and I to her room, which was as palatial as you might expect from the Matriarch.
She went over to the bookcase which I already guessed to be a hidden door before she even reached for one of the books in the bottom shelves.
And… The bookshelf did not swing open like I thought it would.
Not sure if I should be disappointed by that.
Luna flipped open the book to reveal that it contained an inscription carved onto its pages that were folded in a certain order.
She carefully placed it on the ground and unfolded them, revealing an inscription circle large enough for a person to stand on top of.
"Step in here and I will activate the inscription. I have sealed off the room so the only way in is through this teleportation inscription," Luna explained.
Ah, that's something new I haven't seen before.
