Thor beamed at all of them and pulled out four journals. "These are hand crafted on Asgard and no two are ever the same. Had I more time, I would have gotten them a little more detailed, but I knew not when or if I would return. I hope the lack of detail is all right."
He went around the room and handed each of them a different journal. "We use it to communicate with another when we cannot speak. My mother and father once had an argument during a hunting trip through them." That had been interesting to watch. Odin had been flustered the entire time, nearly missing his mark when the beast jumped out.
