Oh, dear, let's maybe not mess too much with the arcane runes etched into some of these walls. One bit in the back got scratched up an hour or two ago and now it's sort of o-o-o-z-i-n-g in a way that makes me a touch queasy just to look at it, and plus also I'm not totally sure I can't still see them when I close my eyes. Maybe those torches will help.
