🍁Nine Ancient Obelisks

Through trial and error, Asmidul discovers that the center of the reaction was his own bedroom, but he cannot determine anything more specific.

Sitting on the edge of the bed, the frail student stretches his tired legs and thinks deeply. How good it is that he didn't take the amulet the day before – if he had instinctively hit the morning guard with it, that would have been a story. He should have thought about it sooner and realized that the device doesn't react to cursed people; otherwise, he wouldn't be able to use it himself. It would be good to test this theory on specific items in his inventory, but the likelihood that the black knight had dropped his helmet or sword somewhere seemed not very real.
But why specifically the bedroom? Does the villain take over the bodies of his victims at night? He committed his deed without even reaching home, and before that, he was wandering around the country. Even if the curse only entered its second stage recently, this doesn't explain the whole picture.

Just in case, he moves the pillows, looks under the mattress, and opens all the cabinets – not really hoping to find anything – and Asmidul goes to the university again. However, he doesn't enter the building itself, so as not to disturb the nameless ones; he only needs the readings of the device during his usual walk to the place and at the entrance to the hall of knowledge.
