Tables are flipped

"Sure... there's a study room in the corner of the level. I don't think anyone's using it at the moment," Pammy says, looking terrified by authority. She must be thinking of ways to convince you of her innocence right then, and you nod and let her lead the way, staring at her tiny ass as you walk. Indeed, apart from that 1 student you had seen earlier, there doesn't look to be anyone else on the level.

As you keep walking, you realize Pammy is walking over to a cluster of shelves in 1 corner of the level instead of taking you to a room.

"Where are we going?" you ask. Pammy doesn't respond immediately, pausing in the middle of a shelf and scanning a row of books until she pulls 1 out by the spine. It's a leather-bound book and it looks old. You can see some symbols and writing on the cover, but it's too dark in this section of the library to make out as Pammy flips to the middle of it starts reading.

"Hey, did you hear me?" you ask, annoyed. Pammy raises a finger to you, telling you to wait. Then, she looks up and mutters some words in a language you've never heard of. "What did you just say?" you ask.

"I was testing something," Pammy says.

"What?!? Okay..." you say, moving to touch your rings to activate them. You're not sure what is going on, but you've had enough of her not following your instructions and decide to use your mind control ring on her. "Lead me to a private room now," you command Pammy.

Then, the strangest thing happens. Instead of doing as you commanded, Pammy's just standing there with the open book in her hand. After a few seconds of you 2 staring at each other, Pammy starts to smile. "It doesn't work on me."

"Huh?"

"Your ring. Or rings. Doesn't work. Try another one," she says.

Confused, you activate your invisibility ring, thinking you'll get the better of her. However, the moment you go invisible, you can feel Pammy's eyes still on you. "Can you see me?" you ask stupidly.

"Of course. Why wouldn't I- Oh, it's an invisibility ring!" she says.

"How are you doing this?" you ask, deactivating your rings.

"I cast a spell to protect myself. I'm a witch. I recognized your rings. I mean, nobody needs to wear 5 rings unless they have magical properties," Pammy says. "So, what do you want?"
