8 The Vessels of Heaven and Hell » by Bornrider2
I recomend watching BBC Robin Hood and Supernatural season eight before reading. It will make more sense. Robin and Guy somehow survived being stabbed and poisoned by Isabella. Sam, Dean, and Cas are sent back to 1192 by Balthazar to stop Lucifer from rising. But can they trick the devil for a second time? Or will Robin and the gang pay the price?
