Melty Spot on the Carpet

Even upon closer examination, you aren't sure what this spot is made of.  Your only other clue in the room is the identically shaped spot on the sealing... and the wet tap you just felt on the back of your neck. 

Unlocked Door with Symbol

You feel a mix of impending doom and surging  realization of your fate.  You've seen this symbol before, and even though you don't know what it means, you know that your life long search is near its end.
