Princesses Celestia and Luna are enjoying a quiet evening at Canterlot Castle when suddenly the guards announce that they have strange, and possibly dangerous, visitors from another kingdom. The guards aren't sure exactly what sorts of creatures these visitors may be, but they're sure that they don't know how to deal with them, so the matter falls to the two princesses. (This is a crossover story involving two characters from the webcomic CHIVALRY AND KNAVERY.)
