Literally. I was running my group through our second session of The Worldwound Incursion when I grabbed my Bestiary 3, knocking my Adventure book off the table. It fell page-down on the floor, and when I picked it up I noticed some of the pages were starting to get loose. That was the only crit I rolled that day.
My book is not damaged beyond the pages falling out, so I'm wondering if there's anything I can do to fix it. I don't know how the pages stay together normally, but that weird black magic is failing. Any advice?
