When in doubt, why not both? With her decisive thinking, they now could see into to the rooms proper. "Alright, let's see…" Cyril put on a mildly serious expression as he focused on the two rooms. The left room didn't feel off, but the closet seemed like a good place to hide things. There wasn't anything else to really look at in there. On the right, there was thick miasma–likely supernatural in origin since it wasn't moving out of the room with the door gone. "The right side looks like a bigger concern at the moment. I can't see anything with all of that in the way. Safety first." Pulling out more talismans, he proceeded to make a line around the door frame and on the floor, creating a temporary barrier. "How about we check the left side first? If anything tries to come out of the other room it'll get blocked for a while."
The room on the left was dusty but thankfully didn't have any traps. The bedding had disintegrated, leaving behind a pile of fibers and brittle wood. Casting a spell of protection over himself, he inspected the closet and then opened it. Cyril held his breath expecting a dart or something to hit him, then opened them when nothing happened. And the contents of the mysterious closet were…books. Very, very old books. The paper was yellow and extremely fragile, practically close to becoming parchment crumbs. There was no water damage, curses, or mold–so it was safe to take. "I wonder what these books are about. I guess we can check after we clear out the other side." So into the bag they went, carefully.
The folklorist then sneezed a few times, sending more dust into the air. From the looks of this place, it was like the room of a boarding school. The room with the ominous 'fog' was quiet, eerily so. With his nose no longer itchy, Cyril prepared to remove the talismans on the threshold before they went in. Immediately he felt the suffocating pressure inside. Whatever was in here was much stronger than the ones that made the maze, but he did his best to keep a straight face. "You might want to close your eyes for a bit, it'll be over in a second." He said, giving Dala a heads-up. Then, he swiftly motioned with the fingers of one hand, causing a pulse of light to burst in the midst of the dark. The moment the first sparks of light appeared, there came a grating screech that sounded like an enraged rusty hinge. The miasma recoiled, writhing and twisting around trying to get away.
The foul smoke then condensed into a vague humanoid shape complete with glowing red eyes giving off an intense feeling of hatred. As the remaining talismans outside the room were still in effect, all they had to do was block the way to prevent it from escaping. The haunted room's interior was no longer obscured, showing similar contents as the other–but with something metallic radiating malicious intent from under the bed. That metallic object moved on its own, the raspy scraping of the floorboards revealing an old double edged short sword now suspended in mid-air within the specter. With a howl, the poltergeist attacked!
