Perimeter Inspection

I surveyed the floorboards below. No hostile entities detected, but precaution is logical. I found two discarded wooden craft sticks near the lower shelf. Using my right grip, I wedged them across each other into a solid cross brace. My left arm, reinforced at the forearm joint, pressed the junction into a slit between heavy hardcovers. Secure fit. It locks the perimeter view. I remain stationed at the highest shelf ledge, scanning every hallway angle. The room remains completely steady.
