Celestia recognized the Commander’s penmanship.  Celestia looked back up to see that her sister had continued stuffing papers and notebooks into her favorite midnight blue saddlebags with the crescent moon embossed in silver thread.  She filled a side pocket with quills and another with a newly sealed inkwell.  Luna squirmed into the straps that held the saddlebags in place.  Once they were all fitted and tight, she experimentally flapped her blue wings a few times to make certain the bags would not interfere mid-flight.  She shot Celestia an eager grin.
