OOC:
I'll flesh it out here a bit more in case it wasn't too clear. I'll helpfully clarify that the astral spirit she met is different from the human insect hybrid vision she saw.
Missy described in as much detail as she could the features of the astral spirit that had traced her and yet did not attack or do anything to her. It took the form of an approximate insectoid shape, but what was notable about it was that the aura that swirled around it looked like an astral representation of some poison or toxin, leeching out from the spirit, casting tendrils all around it, coalescing and dissipating. Missy had the impression that to come in contact with the aura would be injurious to her astral self, and had made no move to approach it.
Missy also recalled for Helios the vision that the spirit showed her, which was an image of Shanto morphing into a human insect hybrid. It was hard for Missy to specify exactly what kind of insect she saw, given the amorphous nature of the image, which was more a thought projection really, being the astral.
