Salazar Slytherin's Scriptorium. Too close and too far at the same time. You are only one door away from the relic Sebastian needs, and the direct message is to use the crucio to open the door.

You look ahead - Sebastian stands impatiently in front of the door and shifting around. He is not afraid to use dark magic. You look back - Ominis walks from corner to corner and seems to be trembling slightly. He's quite pale as it is, but now...

"We don't really have a choice..." Sebastian reminded, twisting his wand between his fingers. "C'mone. You can use crucio on me if you're afraid."
