"Well, how do we open this door anyway?" Emilia asked as she and Althaia were currently trying to force it open with their bare hands.
"Certainly not this way, I guess. Yoru, has anyone told how we are able to enter it?" Iris handed the question over to me, she looked like she also just wanted to brute force it. If the other two hadn't been faster than her, she would have been the one stupidly pushing against it now.
"Actually Lisa told me how to open it, it uses a special locking mechanism. All you have to do is channel a bit of your celestial energy into the big stone that looks like a door knob. This door doesn't even belong to the dungeon itself though. Humans have installed it to keep unknown people from entering it by accident. Seems like that has happened a couple times in the past."
