I had a good head start down an alleyway, so I seized the opportunity to block it with a wall of crystal, and in a moment the entrance was completely filled. It was higher than anyone could jump and thicker than my body was long. “Yes!” I hopped up and down in excited relief after seeing how strong my impromptu blockade was. It should force him to find another route and buy me a few precious seconds. With any luck, I could lose him in the meantime.
