Tell the Anama you wish to join then, and answer all of Meena's questions with a pro-Anama spin. Go back to Alcander, tell him you're ready to join. He will take you upstairs, through the temple, to the altar.
Once at the altar, tell him you've changed your mind about joining; he'll be disappointed, leave, and invite you to show yourself out. Then you can take the scrolls.
This will make them unhappy with you. You will need to find another way down, or else fight your way back through the temple.
