If we know the demons, and we do because we've studied them extensively, they're fast at work repairing any damage that has been done to their precious transporter.$B$BSo, if you want a chance at another darkrune, take our banishing crystal back out there and eliminate more demons.

You might get a darkrune, or you might get something else entirely.
