This was something new

Last night, having finished working within the Astral Temple, I just sat, looking around me. No sooner did the thought cross my mind “This is such a large space for one person alone,” I wasn’t. Crossing the space in front of me, walking from the north to the west was a woman. She didn’t talk; she didn’t even look at me. But there was a sense of “see, you aren’t alone.” Not in the paranoid “you are being watched” sense, neither was it a warm a cuddly sensation. It was just a statement of fact. I was so surprised to see anyone else that I didn’t think to ask her who she was, until she left. I have some ideas, but (after the fact, of course) I feel that it should have occurred to me to simply ask.
