i already at in front of lord lovis's door. but the problem is when i go in, i can't find him in the room and i stuck in the room. can anyone help me on this? thanks.
Looking into the room, from the door, you need to go to your left. There is a body on the bottom of one of the small bridge/duct thingies. It has a reveal spell you'll need. Use the scroll and you should see the way that leads to Lord Lovis.
He is underneath that room, and you have to take an elevator down there. The reveal spell will show you the lever needed to operate the elevator.
