Knock out the nun

You swiftly knock out the nun. Your heart is beating at full speed and your body is full of adrenaline.
A group of nuns enters the room.

"Release her!" one of them commands, but you ask them for the location of the portal. Before you can do anything, they chant in unison, and you feel weak... sleepy... you try to fight, but it's impossible.

No matter how hard you try to fight the sensation, you fall asleep on the floor.

You wake up tied up on a chair. They ask you why you acted like that, they can't understand.
You can confess that you are from another world and you are looking for a portal to return... or you can lie, saying that you are a nun, and you want to see the portal at least one time.
