Charging up the stairs, the party passes through the shimmering light marking the point of no return. At the top, the stairway empties out into another 1/4 circle chamber, much like those found on the first floor. The room appears to be decorated as a sitting room, and contains a coffee table and chairs, as well as a few potted plants. Windows look out upon the city of Orussus.
Looking quickly to your left and to your right, two things immediately leap to your attention. First, you notice that the northeast and northwest walls, which ought to contain the exits to the other rooms on this level, are covered with a chaotic whirling pattern of fire and ice. For a moment, it seems as if you may have found the source of the problem, but then you realize that could not be the case. The fire and ice are far too controlled to be accidental, they must be some sort of intentional barrier... perhaps one of the anti-theft devices mentioned by the puppet in the first room. Also, the wall of fire & ice doesn't seem to be producing any smoke, and it was after all the smoke that initially caused the alarm.
