Sees through Slithers magic

I slithered under the door to find that things were quite different from what I had expected. Instantly I knew that the prisoner was very much alive. Not only that—despite my cloaking magic, she could see me. She stared down at me in a way that left me in no doubt about it. It was also clear that she considered me to be no better than an insect that she would crush under her heel.
