I look around, trying to find someone apart fromus who can explain us what is going on.
You look around.
You are sitting on a magnificent carpet with an intricated multicolored design blending various geometric forms. It seems to be constituted of different types of fabrics, including metallic strands, silver, copper, maybe gold. There is a stain on this carpet. It looks strangely like the vomit substance the creature was spewing, but it seems dead, inanimate, just a shadow of its former self.
You see the huge candle holder next to you, and the little compartments under them, with the little balls of clay of different colors: blue, red and yellow, in separate baskets.
On the eastern wall of the room, you see a huge, round crystal window. This must be part of the giant violet crystal that was part of the pressure-plate trap you saw earlier.
Looking at the southern part of the room, you see the iron door is open. There are different hues of light coming off the corridor, but these aren't the orange, green and blue reflections you were expecting. Instead, these seem to blend reds and yellows, somehow, though the spectrum is more complicated that it first appears the longer you look at it.
At this point, you just realize: the statue of the halfling monk that was set aflame is no longer standing where you were just attempting to light your candles...
