Not explicitly Norse but the Celtic chooser of the slain? Sounds like a Valkyrie to me.The Morrigan - Shape-shifting Celtic goddess of War, Fate and Death. Story in "The GODDESSES / Psychology of Female Power"
A viking ship. "The ship sailed across the murky waters; destruction coming and lean, the boat whisked toward our way.' I gazed up at the ship and instantly knew that the monks could not find anything that could save us.
