Ok. Knowledge keeper here. While Uncle Cedar was dealing with the gremlin we had our own issues. My mom didn't write about it so I'll fill in the gap here
After seeing my mom's new system I helped her navigate it. Her system evolved specifically to her. So it wasn't surprising when I read her new features and status.
After a while I began helping her by collecting every book in the house....that was a lot. As a result her archive skill leveled up to 10. We learned at that point skills at level ten can become passive. When she selected it book collecting became easier because she could collect unowned books within a hundred yards all at once.
As we were sitting outside we heard a sound. Unlike what uncle Cedar hear. What we heard was more akin to a drum being bashed.
We look around each thump reverberated through our bodies. As we go around the front I was the first to notice. Each thump there was a shimmer in the drive way. It was almost imperceptible. But as the hits start getting faster mom and my sister noticed "I think we need to leave" I say
"Agreed" my mother and sister say together. We rush inside. Mom had emptied the house with her inventory. All we really had left were dads old guns and the folding table we had them on.
As we grabbed the car keys it happened. Whatever was beating outside broke the barrier. We all freeze as we hear what sounds like a balloon popping
