It took Nanael a few seconds to notice the burning smell, and by the time she did, there was a fairly large flame on the mattress.  She shrieked and froze for a moment; while she was able to create fire, controlling it and putting it out was not something she could do very easily.  A moment later, realizing that she had to do something, she quickly grabbed the mattress and flung it face-down onto the floor in an attempt to smother and stamp out the flames.<br/><br/>(Let me know if you want a roll for this.)
