I'm trying to get to the final room In VhalSera's Dominion. I'm in the 5th room with the two mirrors. When I click on it, it says "The mirror ripples and pulls at you, but something is stopping it from absorbing you completely." I ran through all the floors again making sure I didn't miss anything, dismissed my merc. I've searched for that particular line and absolutely nothing comes up. There's nothing else to target. I have all the mirror pieces except for the final two in that last room.
